🌊 Oceans on other worlds? Did you know Saturn's moon Enceladus hides an ocean beneath its icy crust? Water interacting with rock on the sea floor could potentially yield chemical reactions that would make the ingredients for life possible. About as wide as Arizona, Enceladus also has the most reflective surface in the solar system. On Oct. 9, 2008, just after coming within 25 kilometers (15.6 miles) of the surface of Enceladus, the Cassini spacecraft captured this stunning mosaic as the probe sped away from this intriguing moon of Saturn.

Set your quasars to STUNNING.💜💙 Astronomers using @NASAHubble recently discovered two quasars that look to be merging into a single object. Astronomers believe that the quasars, which are beacons of light believed to be powered by supermassive black holes, are the cores of two massive colliding galaxies. The quasars in this illustration are only about 10,000 light-years apart, and when their galaxies merge, they will create an even more massive black hole. Quasars play an important role in galaxy formation. By studying these two quasars, scientists can test ideas of how galaxies and black holes develop together. Credits: NASA, ESA, and J.

Above a sea of lights ✨ The Nile Delta sets the scene as the International Space Station (@ISS) floats 250 miles (402 km) above Earth. After living on the orbiting lab for 197 days, on Nov. 8, 2021, the four astronauts of #Crew2 boarded the SpaceX Crew Dragon Endeavour to return to Earth. Before closing out their expedition they took a rendezvous around the ISS. NASA commander @Astro_Kimbrough and pilot @Astro.Megan monitored data as @EuropeanSpaceAgency mission specialist @Thom_Astro captured photos of the International Space Station during the first ever “fly around” of the complex from inside a commercial Crew Dragon. Joined by @JAXAjp astronaut Akihiko Hoshide, the crew successfully splashed down at 10:33 p.m. ET, breaking the record for the longest spaceflight by a U.S.-crewed spacecraft and marked the end of the second crew rotation mission.

We need to talk climate. With records as early as 1880, we have been working together with @NOAA to track Earth’s global temperature as part of our work monitoring climate change. This year contributed to an unprecedented, but well-understood trend in which the last eight years have been the warmest ever recorded. 2021 was tied for the sixth warmest year since our records began. This can be correlated to human activities, like burning fossil fuels which adds to greenhouse gasses, such as carbon dioxide to the atmosphere where they trap more heat. Since about 1850, humans have raised atmospheric CO2 by nearly 50%. Our climate is driven by heat and the energy it carries, influencing our weather, droughts, intense tropical cyclones and more. In 2021, Earth saw several extreme examples of how excess heat in the ocean and atmosphere can influence often devastating, sometimes unexpected, disasters in different parts of the world. Normal temperatures are shown in white. Higher than normal temperatures are shown in red and lower than normal temperatures are shown in blue. Normal temperatures are calculated over the 30 year baseline period 1951-1980. Credit: NASA/Lori Perkins #NASA #NASAEarth #Climate #ClimateChange #Earth #EarthScience #Temperature #Science

👀 Our orbiting X-ray eyes are ready to look into the universe! Last month, our Imaging X-ray Polarimetry Explorer (IXPE) launched into space to observe some of the hottest, most energetic objects in the cosmos. IXPE will measure X-ray polarization, a property of light that will help us study the spin of supermassive black holes and the magnetic fields around powerful pulsars. On Jan. 11, IXPE began observing its first official scientific target: Cassiopeia A, the remains of a massive star that exploded (from Earth's perspective) about 350 years ago. This image shows Cassiopeia A as seen by @NASAChandraXRay, another one of our orbiting observatories that's helping us unravel the mysteries of outer space.

Here we have some happy little clouds and a happy little volcano. 🌥🌋 Italy's Mount Vesuvius breaks through the clouds, as captured by Earth-observing satellite Landsat 8. The the only active volcano on mainland Europe, Vesuvius and was regarded by the ancient Romans as being sacred to the demigod Hercules, son of Jupiter. Because of its proximity to heavily-populated Naples, Vesuvius is closely monitored by a volcanological observatory, which happens to be the world’s first. By dating lava samples, scientists have been able to determine that the volcano has had eight major eruptions, the most recent occurring in 1944.

😎 Livin’ our life like it's golden. Today, @NASAWebb’s iconic honeycomb mirror took its final shape in space, marking the end of the most complex space telescope deployment in history! Swipe for a behind-the-scenes look at some of the team members who made this moment happen – from cleanrooms at @NASAGoddard to mission control at @Space_Telescopes. Made out of beryllium and coated in gold, Webb’s primary mirror is designed to help us see back to some of the first galaxies after the Big Bang. This is the largest and most advanced telescope we’ve ever put into space. Webb’s revolutionary technology will study about 13.5 billion years of cosmic history and help humanity understand our place in the stars. Webb is an international effort between NASA, the @europeanspaceagency, and the @canadianspaceagency. After 20+ years of work, it is well on its million mile (1.5 million kilometers) journey to #UnfoldTheUniverse. 📲 Excited about today? Tell us why! Head to our story to try the “Webb’s Golden Glow” effect and tag us to share your thoughts.

It’s all about perspective 👓 Not to worry, it only looks like these galaxies are colliding from a certain point of view. In reality these galaxies are millions of light-years away from each other. Captured by @NASAHubble’s Wide Field Camera 3, a galaxy located in the constellation Pisces is home to two interesting astronomical events: a Cepheid variable star that brightens and dims regularly and a cataclysmic supernova explosion that's the death of a massive star. Because both astronomical events have predictable luminosities, they help astronomers measure how fast our universe is expanding Credit: NASA/@EuropeanSpaceAgency/Hubble, D. Jones, A.

🌍 When Earth looks like another world If it weren't for the blue sea on the horizon, this might look like a photo of Mars or a faraway planet from science fiction. Instead, it's actually an image of the Libyan Desert, one of the most arid parts of the Sahara Desert in northern Africa. Taken by an External High-Definition Camera (EHDC) on the International Space Station in February 2021, this photograph shows the windswept dunes and darker sandstone plateaus of Libya's Fezzan region, with the Mediterranean shining in the far distance. The EHDC is one of many cameras and scientific instruments on the @ISS that are continually monitoring the Earth from space—not just to take incredible pictures like this one, but to observe our environment and help us protect our home planet.

New Year, new Moon! 🌚 Kicking off 2022, stargazing is at its best on the nights around the new Moon on Jan. 2. Later that night, catch the peak of the Quadrantid meteor shower. Look for meteors after midnight local time, after the constellation they appear to originate from, Boötes, rises above the horizon. ☄️ This tends to be one of the better meteor showers of the year and often produces bright meteors called fireballs! A few days later, look for the Moon with Jupiter on Jan. 5 in the west, and with Mars and Venus on Jan. 29 in the east. Venus is now appearing in the morning after being "the Evening Star" in 2021, and Mars is returning to the skies after its solar conjunction last fall, where it passed behind the Sun as seen from Earth.

🚀 Here be dragons 🐉 As we get ready for the new year, we're continuing to make space travel more reliable and less expensive—with the help of our commercial partners. In 2021, our first @SpaceX crew rotation flight to the International Space Station (Crew-1) safely splashed down on Earth after 168 days in orbit, and two more Commercial Crew missions lifted off to open new frontiers on our orbiting laboratory. Next up: Crew-4, currently scheduled to launch in April 2022. In this image, the SpaceX Crew Dragon spacecraft Endeavour is seen departing the @ISS on November 8, 2021, with four astronauts from NASA, @JAXAJP, and the @EuropeanSpaceAgency preparing to return home after their successful six-month Crew-2 mission.

Closing out the year with a bang 💥 The @NASAHubble space telescope captured a side-on view of a barred spiral galaxy roughly 57 million light-years from the Milky Way in the constellation Centaurus. In 2014, a sudden flare of light caused by the explosion accompanying the death of a massive star in our galaxy was discovered by amateur astronomers who are part of the Backyard Observatory Supernova Search in New Zealand. This wealth of knowledge provided by Hubble paves the way for future science as @NASAWebb makes its way to Lagrange Point 2, where it will begin its orbit. Hubble’s Advanced Camera for Surveys and Wide Field Camera 3 have made connections between young stars and the clouds of cold gas in which they form. Webb’s ability to observe at infrared wavelengths will be able to peer through the clouds of gas and dust in stellar nurseries and observe the fledgling stars within. #NASA #Hubble #Spiral #Galaxy #Space #AstroPhotography #Astronomy #Stars #JWST #UnfoldTheUniverse #NewYear #NewDiscoveries

Staying close to those deer to us 🦌❄️ This winter scene captures the Sápmi region, which stretches across parts of Finland, Sweden, Norway and Russia. This region is the ancient home of the Sami, Europe’s only recognized indigenous people. About 80,000 to 100,000 Sami are spread across the four countries and have lived a nomadic life of hunting, gathering, and reindeer herding. In fact, this is one of the few places on Earth where deer have been domesticated. 🦌An estimated 500,000 reindeer live in Scandinavia, with most of them tended and herded by the Sami.🦌 The image above is part of a global composite assembled from data acquired in 2016 by the @NOAA and @NASAEarth Suomi National Polar-orbiting Partnership. This nightime view was made possible by the “day-night band” of the Visible Infrared Imaging Radiometer Suite, which is sensitive enough to measure nighttime light emissions and reflections to distinguish the intensity of lights and observe how they change.

Goodnight Moon 🌙 A waxing crescent Moon is pictured from the International Space Station (@ISS) during an orbital sunset as it flew 268 miles (431 km) above the Pacific Ocean east of New Zealand. Above the surface of the Earth, a brilliant sequence of colors roughly denotes several layers of the atmosphere. Deep oranges and yellows appear in the troposphere, which contains over 80 percent of the mass of the atmosphere and almost all of the water vapor, clouds, and precipitation. The pink to white region above the clouds appears to be the lower stratosphere; this atmospheric layer generally has few or no clouds. Above the stratosphere, blue layers likely mark the transition between the middle and upper atmosphere as it gradually fades into the blackness of outer space.

“We’ve crossed the solar system and sent ships to the stars. But we continue to search. We can’t help it.” – Carl Sagan Like a gift to the cosmos, the James Webb Space Telescope was launched atop an Arianespace Ariane 5 rocket from Europe’s Spaceport in French Guiana on Dec. 25, 2021, at 7:20 a.m. EST (12:20 UTC). The largest, most complex, and most powerful space telescope ever built, Webb will begin a nearly two-week process of unfolding its instruments, mirrors, and tennis-court-sized sunshield as it cruises through deep space to its destination 1 million miles (1.5 million kilometers) from Earth. For nearly 29 days, it will journey to Lagrange point 2, a gravitational well that lets the telescope stay in line with Earth as it moves around the Sun. A joint effort with the @EuropeanSpaceAgency, the @CanadianSpaceAgency, and @space_telescopes, Webb will study infrared light with much greater clarity than ever before and help reveal cosmic history – from within our solar system to the most distant observable galaxies in the early universe, to everything in between. But perhaps what’s most interesting is that we don’t yet know what Webb will discover. Will we have more questions? Time will tell. We'll be ready.

"The vast loneliness is awe-inspiring, and it makes you realize just what you have back there on Earth." – Jim Lovell On Dec. 24, 1968, Apollo 8 astronauts Frank Borman, Jim Lovell, and Bill Anders became the first humans to orbit the Moon and the first to witness the Earth rising above the Moon's barren surface. That evening they held a live broadcast from lunar orbit, in which they showed pictures of the Earth and Moon as seen from their spacecraft. The mission is known for this iconic "Earthrise" image, snapped by Anders, which would give humankind a new perspective on our home planet. Anders has said that despite all the training and preparation for an exploration of the Moon, the astronauts ended up discovering Earth. Fifty-three years later, we celebrate the moment by looking back on this image.

❄️ Spot the stellar snowflakes on the cosmic Christmas tree 🎄 About 2,500 light-years from Earth, stars are being born in a region of space known as the Christmas Tree Cluster. Seen in the infrared (just beyond the range of visible light) by NASA's Spitzer Space Telescope, these infant stars (less than 100,000 years old) appear as pink and red specks near the center of this photo, evenly-spaced in a spoke-like pattern that gives them the name of the Snowflake Cluster. Spitzer wrapped up its operations in 2020—but next year, @NASAWebb is set to give us an unprecedented look at the cosmos in infrared, gazing into star clusters, black holes and the most distant galaxies in our universe after it lifts off, currently scheduled for this Christmas Eve. Stay tuned for more stellar sights from our orbiting observatories! Credit: NASA/JPL-Caltech/P.S.

🔭 Look, Ma, four cavities! A pair of supermassive black holes could be behind a set of cosmic cavities, or bubbles, recently spotted by our orbiting @nasachandraxray observatory. The four bubbles were detected 3.9 billion light-years from Earth in a galaxy cluster, a collection of hot gas, dark matter and thousands of galaxies that is among the largest structures in the universe held together by gravity. Many galaxy clusters have a pair of cavities, caused by a single black hole spewing out twin streams of matter from the cluster's center, but this is the first known instance of a galaxy cluster with four massive bubbles instead of two. Astronomers hypothesize that a single black hole which quickly flipped on its side could also be behind this galactic oddity. These images show the galaxy cluster RBS 797 as seen in X-rays by Chandra, visualized here in blue and white, alongside a photo of the cluster as seen in visible light by @nasahubble.

🚀☀️ We've touched the Sun! For the first time in history, a spacecraft has entered the solar corona—the point in the Sun's atmosphere where its magnetism and gravity are strong enough to stop solar material from escaping. Our Parker Solar Probe, launched in 2018, first swooped through the Sun's corona for a short period earlier this year. Just as landing on the Moon allowed scientists to understand how it was formed, touching the very stuff the Sun is made of will help scientists uncover critical information about our closest star and its influence on the solar system. For example, Parker Solar Probe's journey through the corona is already helping astrophysicists understand the origins of unusual zig-zags found in the solar wind that flows past Earth and planets beyond. Parker has already made ten fly-bys of the Sun and will continue to swirl ever-closer as it collects data over the next four years. The image seen here was taken by our Solar Dynamics Observatory in March 2012, as a giant eruption of solar material exploded off of the surface on the Sun's right side.

Baby, it’s icy outside. 🧊 This icefield of the southern Andes mountains was captured by an astronaut aboard the International Space Station (@ISS). The mountain peaks here reach high enough and temperatures remain cold enough year-round that permanent ice persists amid a warming world. It was significantly larger about 18,000 years ago, during the coldest phase of the last Ice Age, covering almost the entire view in this image—an enormous area considering that the present icefield is more than 100 kilometers (60 miles) long. Glacial ice moves slowly downhill under its own weight. As it flows, it cuts valleys into the underlying rocks. There have been several ice ages in the past, and scientists now know that the lakes at the top of this image and the network of valleys (fjords) at the bottom were gouged out by the erosion of moving glacial ice when the icefields were much larger. In a recently published survey of glaciers, scientists showed that the Patagonian icefields follow the global trend of ice melting and loss. Ice losses here have occurred because air temperatures have been increasing along the length of the Andes, even while there has been a small increase in precipitation (snow) that feeds the glaciers.

📸 😉 Get my good side. If you’re a galaxy, that tends to be all sides. Take this edge-on view captured by @NASAHubble for example. This spiral galaxy’s tightly wound spiral arms steal the show, revealing bands of stars and dark clouds of dust. It’s located 230 million light-years away in the constellation Aquila and lies close to the plane of the Milky Way. So close that foreground stars from our own galaxy have crept into the image – the two prominent stars in front of this galaxy are interlopers from within the Milky Way. The spikes surrounding these stars are imaging artifacts, called diffraction spikes. They are the result of starlight interacting with the structure that supports Hubble’s secondary mirror.

See you space cowboy... On Dec. 2, @NASAAstronauts @Astro_Kayla and @AstroMarshburn stepped outside of the International Space Station (@ISS) and got to work amongst incredible Earth views, while successfully installing an S-band Antenna and stowed the failed antenna. The 6 hour and 32-minute spacewalk was the fifth spacewalk for Marshburn and the first for Barron, and was the thirteenth spacewalk of the year. Last month marked the space station’s milestone of 21-years of continuous human presence, providing opportunities for unique research and technological demonstrations that help life here on Earth and prepare for future missions to the Moon and Mars. During that time: ▪️249 people from 19 countries visited the orbiting lab ▪️3,000 research investigations were hosted ▪️245 spacewalks were conducted ▪️64 days, 12 hours and 26 minutes were spent in spacewalks by crew members Credit: NASA/Tom Marshburn/Kayla Barron #NASA #Spacewalk #Astronauts #Earth #Earthviews #Space #Workviews #Officefortheday #remotework

We're taking science in a new direction ⬆️ #IXPE, our Imaging X-Ray Polarimetry Explorer, lifted off from @NASAKennedy at 1:00 a.m. EST (06:00 UTC) this morning. Orbiting about 375 miles (600 km) above Earth's equator, IXPE will observe the universe using polarized X-rays, a unique property of light rarely studied in space. Polarized light occurs when light waves bounce off matter in particular ways, causing their electric fields to all vibrate in the same direction.

🚀 Our Laser Communications Relay Demonstration (LCRD) is space-bound! Today at 5:19 AM EST (10:19 UTC), LCRD launched on a @ULALaunch Atlas V rocket from the Cape Canaveral Space Force Station in Florida as part of the @SpaceForceDOD Space Test Program 3 mission. LCRD will showcase the unique capabilities of optical communications which increases bandwidth for communicating data in space while reducing size, weight, and power requirements. Laser communications – also called optical communications because of the use of infrared light to send information – offers higher data rates than traditional radio frequency systems, enabling more data to be sent with each transmission. This new way of communicating with spacecraft could expand the possibilities of what we could learn from future missions across the solar system. Once operational in geosynchronous orbit – about 22,000 miles above Earth – LCRD will demonstrate space-to-ground laser communications linking ground stations in Hawaii and California. Later in its mission, LCRD will receive and transmit data from an optical terminal that we will place on the International Space Station (@ISS). You can learn more about the LCRD mission by tuning in to the new season of The Invisible Network podcast, wherever you get your podcasts.

🌞 🌗🌍 Have you ever seen a total solar eclipse? How about seeing a total solar eclipse FROM SPACE? Our robotic and human explorers are here to help. On Dec. 4, 2021, the Deep Space Climate Observatory (DSCOVR) spacecraft captured the Moon's shadow as it passed over Antarctica, home to penguins and a handful of scientists. Shaped like a cone extending into space, the shadow has a circular cross-section most easily seen during a solar eclipse. People in parts of Namibia, South Africa, New Zealand, and the Falkland Islands were treated to a partial eclipse. How about seeing it from another perspective? Astronaut Kayla Barron snapped images of the eclipse from inside the International Space Station (@ISS). Visible in the foreground is a Russian segment of the orbiting laboratory. A solar eclipse happens when the Moon moves between the Sun and Earth, casting a shadow on Earth, fully or partially blocking the Sun’s light in some areas. For a total solar eclipse to take place, the Sun, Moon, and Earth must line up exactly. A joint [email protected] observatory, DSCOVR orbits about a million miles from Earth and takes a new picture of Earth every two hours with its camera called EPIC – the Earth Polychromatic Imaging Camera. Launched in 2009, DSCOVR monitors changes in the solar wind and provides space weather forecasts and alerts for solar storms that could temporarily disrupt power grids and GPS.

🌀 And we’re spiraling! Our @NASAHubble Space Telescope captured this image of a spiral galaxy in the constellation Virgo, roughly 120 million light-years from Earth. This richly detailed image was snapped by the Hubble’s Wide Field Camera 3, capturing a wide range of ultraviolet, visible, and infrared wavelengths. This galaxy could be described as a “weakly-barred spiral galaxy,” which means the spiral arms of the galaxy radiate from a central bar of gas and stars. Bars occur in roughly half of spiral galaxies, including our own galaxy, the Milky Way. Credit: NASA/Hubble & @EuropeanSpaceAgency, A.

🔭 What can you see in the December skies? A string of sunset planets, a chance to see 2021's brightest comet, and the annual Geminid meteor shower.⁣ ⁣ On December 6 through 10, look westward following sunset for the Moon visiting Venus, Saturn, and Jupiter in turn. The Moon's crescent fills out as it appears higher in the sky each evening over the course of the week. On December 12, recently-discovered comet Leonard will be at its closest to Earth, just a couple of weeks before it reaches its closest distance from the Sun. You'll probably need binoculars to spot it.⁣ ⁣ Finally, this year's Geminid meteor shower peaks overnight on December 13-14, and is best observed after the Moon sets. The meteors appear to radiate from the constellation Gemini, which you'll find high in the west.

You and I collide 💫 Mounded, luminous clouds of gas and dust glow in this @NASAHubble image of a Herbig-Haro object known as HH 45. Herbig-Haro objects are a rarely seen type of nebula that occurs when hot gas ejected by a newborn star collides with the gas and dust around it at hundreds of miles per second, creating bright shock waves. HH 45 is located in the nebula NGC 1977, which itself is part of a complex of three nebulae called The Running Man. These three nebulae are reflection nebulae, which means that reflect light from nearby stars instead of emitting light on their own, like a streetlight illuminating fog. Credit: NASA, ESA, and J.

Wish you were here ✨ Our Curiosity Mars rover was thinking of you and decided to send you a postcard of its most recent perch on the side of Mars’ Mount Sharp. Keeping in touch with loved ones is important! Curiosity captures a 360-degree view of its surroundings with its black-and-white navigation cameras each time it completes a drive. To make the resulting panorama easier to send to Earth, the rover keeps it in a compressed, low-quality format. But when Curiostiy saw the view from its most recent stopping point, the scene was just too pretty not to capture it in the highest quality that the navigation cameras are capable of. The beauty of the landscape was so inspiring, in fact, that the mission team decided to add a little flair: they combined two versions of the black-and-white images from different times of the day and added colors to create a rare postcard from the Red Planet.

🚀 We're on our way to nudge an asteroid! Our DART spacecraft lifted off at 1:21 a.m. EST (6:21 UTC) this morning, beginning its 10-month journey to the small "moonlet" Dimorphos. Late next year, the vending machine-sized ship will smash into Dimorphos at more than 15,000 miles an hour (24,000 kph), altering its orbit very slightly around the larger asteroid Didymos. Dimorphos does not pose a threat to Earth, either before or after DART's impact, but the data we collect from DART's collision will help us design spacecraft to deflect any future asteroids or near-Earth objects that ever threaten our home planet. Designed by @JohnsHopkinsAPL, DART lifted off on a @SpaceX Falcon 9 rocket from @Vandenberg_SFB in California.

Did someone order a dark ‘n stormy? 🌌 About 1,400 light-years from Earth lies the largest star-forming cluster in the constellation of Orion, the Flame Nebula. The dark and dusty heart of nebula, pictured here, is where star a cluster resides, mostly hidden from view. Nearby (but not visible in this image), is the bright star Alnitak, the easternmost star in the Belt of Orion. Radiation from Alnitak ionizes the Flame Nebula’s hydrogen gas. As the gas begins to cool from its higher-energy state to a lower-energy state, it emits energy in the form of light, causing the visible glow behind the swirled wisps of dust.

A blue sunset on the Red Planet Our Perseverance Mars rover has taken its first picture of a sunset! This image was captured on Nov. 9, 2021, by the rover's Mastcam-Z camera system on the 257th Martian day, or sol, of the mission. While this is the first sunset imaged by Perseverance, Our robotic explorers have been looking up at the Sun from the surface of the Red Planet since the 1970s. Vikings 1 and 2; the Pathfinder and Phoenix landers; Spirit, Opportunity and Curiosity rovers have sent back sunrise and sunset scenes. Martian sunsets typically stand out for their distinctive blue color. Fine dust in the atmosphere permits blue light to penetrate the atmosphere more efficiently than colors with longer wavelengths. But this sunset looks different: less dust in the atmosphere resulted in a more muted color than average. The color has been calibrated and white-balanced to remove camera artifacts.

🏊‍♂️ Down for a dip in the Cosmic Reef? Nicknamed the Cosmic Reef because it resembles an undersea world, this is a vast star-forming region in the Large Magellanic Cloud, a satellite galaxy of the Milky Way! The sparkling centerpiece of the orange nebula (NGC 2014) is a grouping of bright, hefty stars, each 10 to 20 times more massive than our Sun. By contrast, the seemingly isolated blue nebula at upper right (NGC 2020) has been created by a solitary mammoth star 200,000 times brighter than our Sun! Released in April 2020 to celebrate @NASAHubble’s 30th anniversary, the Cosmic Reef showcases the beauty and mystery of space in this complex image of starbirth.

What do you see in Jupiter's turbulent clouds? On Sept. 2, 2021, our Juno mission to Jupiter captured this view of striking cloud bands and swirls in the giant planet’s mid-southern latitudes. The dark, circular vortex near the center of the image is a cyclone that spans roughly 250 miles (about 400 kilometers). The color at its center is likely to be the result of descending winds that cleared out upper-level clouds, revealing darker material below. Citizen scientist Brian Swift used a raw JunoCam image digitally projected onto a sphere to create this view. It has been rotated so that north is up. At the time, the spacecraft was about 16,800 miles (about 27,000 kilometers) above Jupiter’s cloud tops, at a latitude of about 31 degrees south.

✨A thing of mystery and beauty. This complex nebula is filled with glowing gases, lanes of dust, and stars of all ages—but what interests astronomers the most is what ISN'T there. One of its most distinctive features is the dark, starry gap called a “superbubble,” visible in this @NASAHubble image in the upper central region. The hole is about 250 light-years wide and its presence is still something of a mystery. Stellar winds expelled by massive stars in the bubble's interior may have driven away the gas, but this is inconsistent with measured wind velocities in the bubble. Another possibility, since the nebula is filled with massive stars that would expire in titanic explosions, is that the expanding shells of old supernovae sculpted the cosmic cavern. 📲 Check out our Instagram story to screen shot this as your new wallpaper!

🟥 Seeing a lot of RED in your feed today? This recent image from @NASAHubble swiftly captured our attention. These cosmic ribbons of gas have been left behind by a titanic stellar explosion called a supernova. It is thought to be the remnant of a Type 1a supernova, the death of a white dwarf star. A true chart topper, this supernova remnant was found to have hotter gas and shine brighter in X-rays than the remnant of a typical Type 1a supernova. Astronomers suspect the white dwarf star was more massive than expected – heavier stars expel more gas – which also means it would have died earlier in its lifecycle. Credit: NASA, ESA, and Y.

The cat's pajamas or totally pawesome? Either way, here's the Cat's Paw Nebula 🐾😻 Our Spitzer Space Telescope captured the image of this nebula so named for the large, round features that resemble a feline footprint. Bright red bubbles and green clouds are highlighted using data from two of Spitzer's instruments. Spitzer was an infrared telescope, and infrared light is useful to astronomers because it can penetrate thick clouds of gas and dust better than optical light (the kind visible to the human eye).

📸 New album just dropped: EARTH You’re looking at the first images captured by #Landsat 9, a joint Earth-observing mission in partnership with @USGS. Since 1972, Landsat data has provided a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global-change research. Landsat images have also proved invaluable to the International Charter: Space and Major Disasters, supporting emergency response and disaster relief to save lives. With the addition of Landsat 9, the Landsat program’s record of land imaging will be extended to over half a century. Swipe through to see: 1. The remote coastal islands and inlets of the Kimberley region of Western Australia – Landsat 9’s first image. 2. The Navajo Nation. Communities like these in the Western U.S. rely on Landsat and other satellite data to help monitor drought conditions and manage water resources. 3. The glaciers and meltwater lakes of High Mountain Asia in the Himalayas. Glaciers provide drinking water for communities in the region. Landsat helps track the growth and changes to the glaciers and lakes. 4. Both Detroit, Michigan and Winsor, Ontario featuring Lake Erie. In warmer months, Landsat 9 will help monitor potentially harmful algal blooms in lakes like these. 5. The white sands of Pensacola Beach and the Florida Panhandle. Landsat and other remote sensing satellites help track changes to US coastlines, including urban development and potential impacts of rising sea levels.

Did the Helix Nebula catch your eye? 👁️ All eyes are on this eerie Spitzer Space telescope image that shows infrared radiation from the well-studied Helix Nebula, a mere 700 light-years away in the constellation Aquarius. The two-light-year diameter shroud of dust and gas around a central white dwarf, is an example of a planetary nebula, one of the final stages in the evolution of a Sun-like star. The dust makes this cosmic eye gleam red. The nebular material was ejected from the star many thousands of years ago, the close-in dust could be generated by collisions in a reservoir of objects, like our own solar system’s Kuiper Belt or cometary Oort cloud. Formed in the distant planetary system, the comet-like bodies have otherwise survived the dramatic late stages of the star’s evolution. Keep an eye out as we highlight some of our favorite nebulae this November! 👀 Image credit: NASA, JPL-Caltech, Kate Su (Steward Obs, U.

Pizza planet? No, it’s Jupiter. But we’ve just learned some incredible new science from the supreme planet. New findings released on Oct. 28 from our #JunoMission orbiting Jupiter are giving us a fuller picture of the planet’s turbulent atmosphere. Our Juno spacecraft peers beneath Jupiter’s cloud tops to scope out its many jet streams and storms, including the iconic Great Red Spot and once again it has uncovered new science. Here’s a taste of what we now know: ▪️Some storms extend 60 miles (100 kilometers) deep ▪️The Great Red Spot is over 200 miles (350 kilometers) deep ▪️Jupiter’s polar cyclones barely change location over time ▪️Its distinctive bands might form from ammonia and water traveling up and down Juno launched in 2011 and reached Jupiter about five years later. Now in a wide orbit around the planet, the spacecraft conducts regular close passes, attempting to uncover what lingers beneath the gargantuan orb’s clouds. Citizen scientists use the probe’s JunoCam to process images, giving researchers a better view of Jupiter’s atmosphere. Studying this incredible planet helps us better understand the origin – and evolution – of the solar system.

Spotted: signs of a potential planet about 28 million light-years away 🔎 🪐 For the first time, astronomers may have detected an exoplanet candidate outside of the Milky Way galaxy. Exoplanets are defined as planets outside of our solar system. All other known exoplanets and exoplanet candidates have been found in the Milky Way, almost all of them less than about 3,000 light-years from Earth. This new result is based on transits, events in which the passage of a planet in front of a star blocks some of the star's light and produces a characteristic dip. Researchers used our @NASAChandraXray Observatory to search for dips in the brightness of X-rays received from X-ray bright binaries in the spiral galaxy Messier 51, also called the Whirlpool Galaxy (pictured here). These luminous systems typically contain a neutron star or black hole pulling in gas from a closely orbiting companion star. They estimate the exoplanet candidate would be roughly the size of Saturn, and orbit the neutron star or black hole at about twice the distance of Saturn from the Sun. This composite image of the Whirlpool Galaxy was made with X-ray data from Chandra and optical light from our @NASAHubble Space Telescope. Credit: X-ray: NASA/CXC/SAO/R.

This rocket and spacecraft are now planned to lift off in February 2022 on the @NASAArtemis I mission, an uncrewed flight test that will send Orion thousands of miles beyond the Moon, farther than any spacecraft built for humans has ever flown, over the course of about a three-week mission. In later #Artemis missions, we plan to land the first woman and the first person of color on the surface of the Moon. We're working towards a long-term lunar presence, and eventually, sending humans to Mars. Credit: NASA/Kim Shiflett #NASA #Orion #SpaceCoast #RocketScience #Space #SLS #Rocket #News #Artemis #Moon

I mean… 😍 If you have a chance tonight, catch a glimpse of the full Moon. The nearly full Moon is seen here as it rises from The Observatory at America’s Square in Washington, DC on Oct. 19, 2021. The full Moon after the Harvest Moon is known as the Hunter's Moon. The earliest use of the term "Hunter's Moon" cited in the Oxford English Dictionary is from 1710. According to the Farmer's Almanac, with the leaves falling and the deer fattened, it is time to hunt. The Maine Farmer's Almanac first published Native American names for the full Moons in the 1930s. Over time, these names have become widely known and used. According to this almanac, as the full Moon in October the Algonquin tribes in what is now the northeastern U.S. called this the Travel Moon, the Dying Grass Moon, or the Sanguine or Blood Moon. Some sources indicate that the Dying Grass, Sanguine, and Blood Moon names are related to the turning of the leaves and dying back of plants with the start of fall. Others indicate that the names Sanguine or Blood Moon are associated with hunting to prepare for winter.

There is magic in the night 🔮 Above the Indian Ocean in between Australia and Antarctica, approximately 273 miles (440 kilometers) above Earth, astronauts aboard the International Space Station (@ISS) captured this vivid green light show over the southern hemisphere of the planet. Named for the Roman goddess of dawn, an aurora is a captivating display of light in the night sky caused by atoms colliding to create brilliant bursts of light. When we see a glowing aurora like the one pictured, we are watching a billion individual collisions, lighting up the magnetic field lines of Earth along the northern and southern hemispheres - aurora borealis also known as the “northern lights” and aurora australis also known as the “southern lights.” Credit: NASA #NASA #AuroraAustralis #PlanetEarth #SouthernLights #LightShow #space #aurora

🌌 What mysteries await us at the heart of our home galaxy? This panorama of the Milky Way's galactic center brings together data from our orbiting @nasachandraxray observatory and the MeerKAT radio telescope in South Africa. The orange, green, blue and purple areas of this image correspond to different levels of X-ray energy, with radio waves shown in lilac and gray. Combining observations from across the electromagnetic spectrum reveals the presence of intertwined threads of energy up to 20 light-years long, hypothesized to be held together by thin strips of magnetic fields. Learning more about these threads may help us study space weather, like the solar wind that blows through our solar system, and better understand the cosmic tapestry of the Milky Way's core.

The journey of 4 billion miles (6.4 billion kilometers) begins with a single launch. 🚀 The @ULALaunch Atlas V rocket lifted off successfully at 5:34 a.m. EDT (09:34 UTC), beginning #LucyMission's 12-year journey to the Trojan asteroids, ancient space rocks that share an orbit with Jupiter around the Sun. The rocket launched from Cape Canaveral Space Force Station in Florida, carrying the first spacecraft to ever study the Trojan asteroids, which are thought to be time capsules from the birth of our solar system more than 4 billion years ago. Shortly after launch, the Lucy spacecraft separated from the rocket’s Centaur upper stage to fly freely for the first time. After Lucy's solar arrays unfurled, cheers and applause erupted from the launch teams. And Lucy went off to uncover secrets of our universe.

Don’t be average; be savage. 💥 The fierce, swirling chaos of dust and gas in this @NASAHubble image is from a massive star that exploded, spewing its gaseous layers out into an already turbulent region of space. The supernova in the photo is still young, but ruthlessly destroying the ambient gas clouds that might otherwise collapse and form stars. It's a savage. The supernova remnant is part of the star-forming Large Magellanic Cloud (LMC) region, a galaxy 160,000 light-years from the Milky Way. The LMC provides excellent opportunities to study active star formation.

❤️ We love Lucy.⁣ ⁣ Our #LucyMission, that is. Targeted to launch on Oct. 16 at 5:34 a.m. EDT (09:34 UTC) our Lucy spacecraft will lift off to the sky -- with diamonds -- aboard a @ULALaunch Atlas V rocket. Seen here is its ride to space as it is rolled out to the launch pad at Cape Canaveral Space Force Station in Florida. ⁣ ⁣ Lucy will be the first spacecraft to study Jupiter's Trojan asteroids, two clusters of ancient space rocks that are leftovers of planetary formation. Like the mission's namesake – the fossilized human ancestor, "Lucy," whose skeleton provided unique insight into humanity's evolution – Lucy will revolutionize our knowledge of planetary origins and the formation of the solar system. On board are a suite of instruments that will study these worlds, including a diamond beamsplitter that splits beams of light so scientists can determine the temperatures and surface properties of an asteroid.⁣ ⁣ Our live Lucy launch coverage begins Sat., Oct. 16 at 5:00 a.m. EDT (09:00 UTC).

You’ve heard of the Hidden Figures. But have you heard of another hidden figure named Mary Golda Ross?⁣ ⁣ Born in 1908, Ross was a Native American and member of the Cherokee Nation. After earning a master's degree in 1938, she eventually moved to California in 1941, where she landed a job as a mathematician at Lockheed, working on the P-38 Lightning fighter plane. She worked her way up the ranks at Lockheed and become the only woman among on the original team at Skunk Works.⁣ ⁣ As a mathematician and engineer, she wrote a number of professional and theoretical works and was one of the authors of the NASA Planetary Flight Handbook Vol. III, about space travel to Mars and Venus.⁣ ⁣ Image 1: This image of Venus is a composite of data from NASA's Magellan spacecraft and Pioneer Venus Orbiter.

We see you, baby star! 🤩 Since modern astronomical observations began, we've been studying the subtle changes that happen in the birthplaces of stars and planets. Cosmic timescales can be very long, however the celestial objects in this @NASAHubble photo have changed in a relatively short amount of time. The bright spot located at the right edge of the fan-shaped object is a young star nicknamed “PV Cep.” A photo of PV Cep taken in 1952 showed a nebulous streak, similar to a comet’s tail, but this had vanished by the time new images of the star were obtained some 25 years later. Instead, the blue fan-shaped nebula seen here had appeared. Twenty-five years is a very short period on cosmic timescales! Astronomers think the mysterious streak may have been a temporary phenomenon – perhaps the remnants of a massive stellar flare. PV Cep is located in the northern constellation of Cepheus at a distance of over 1600 light-years from Earth. Credit: ESA/Hubble & NASA.

It takes two to tango 💃 @NASAHubble captures the delicate dance between two interacting galaxies. Setting the scene at more than 100 million light-years away from Earth, the lower galaxy clearly tugs at the galaxy on the upper right, which appears to extend one spiral arm downward. The two galaxies are classified as spiral, but their shapes appear different due to their orientation in respect to Earth. Astronomers think that collisions between spiral galaxies like this can lead to the formation of another type of galaxy, known as elliptical galaxies. As extremely massive and energetic these collisions may be, it is no quickstep. Collisions like these often take place over hundreds of millions of years, so we should not expect this dancing pair to look any different during the course of our lifetimes.

Ever wonder what Mars might have looked like billions of years ago? So do we! Today, the Martian surface is sorely lacking in stunning water views like this, but our Perseverance Mars rover is busy exploring Jezero Crater, where scientists believe about 3.5 billion years ago a lake and river delta may have flowed! The rocks in this photo adorn the shoreline of Lake Salda in Turkey, an area that scientists believe the #RedPlanet may have resembled billions of years ago. Formed over time by microbes that trap minerals and sediments in the water, this waterfront location provides some of the oldest known fossilized records of life on our planet. Scientists hope by studying microbial fossils on Earth, they might be better able to spot signs of microbial life from the water and sediments that flowed on Mars billions of years ago.

🌟 What a way to make an entrance!⁣ ⁣ Our Hubble Space Telescope photographed this dramatic birth of a star. Enrobed in a cloak of dust and gas, the newborn blasted super-hot materials into its surroundings to announce their arrival.⁣ ⁣ This star does not lie in a galaxy far, far away, but rather right inside our home galaxy, the Milky Way. @NASAHubble observed this event in infrared light, which enabled the telescope to peer through the gas and dust cocooning the newly forming stars and capture a clear and colorful view.⁣ ⁣ These young stars are ideal targets for our upcoming James Webb Space Telescope (@NASAWebb), which will have even greater infrared wavelength to see deeper into the Universe and capture the formation of galaxies.⁣ ⁣ Credit: NASA⁣ ⁣ #Stars #MilkyWay #Astronomy #NASA #HerbigHaro

🎶 Spiderweave, Spiderweave, helps our heat shields overachieve 🕸️ With the possibilities of future missions to Mars and beyond, scientists are finding new ways to make it safer for larger vehicles to safely pass the atmosphere of more distant locations. Our Adaptable, Deployable, Entry and Placement Technology, or ADEPT, is testing a next-generation heat shield design for delivering jumbo-size cargo to planetary surfaces. Meet: Spiderweave. The new 3D-woven carbon fabric can open up like an umbrella and withstand temperatures greater than 3,000 degrees Fahrenheit (about 1,650°C). Spiderweave uses a new design architecture where materials are continuously woven into the heat shield’s fabric, avoiding issues like points of increased stress and other rifts within the material. Where saving space and enabling safer atmospheric entries are top priorities, Spiderweave can be packed up at launch and stored in a compact space when sending science to other worlds. In this image, the ADEPT Spiderweave material is put to the test in the arc jet facilities at @NASAAmes, which simulates the intense heating spacecraft experience during atmospheric entry.
