Before our Artemis II astronauts lift off on their journey around the Moon next year, find out what it takes to build a mission like theirs from the ground up. Episode 1 of Moonbound is live—and free to watch on NASA+: https://t.co/Is3l2PRkBk

He’s red for an amazing reason! This dwarf galaxy named Markarian 178 has a mostly blue hue, but a collection of rare massive stars gives the galaxy glowing patches of red. Learn more about this @NASAHubble image: https://t.co/2xgYU9vQxi

From LEO to deep space, NASA keeps America leading on every frontier 🇺🇸 🧑‍🚀 @rookisaacman advances to Senate floor 🔑 @Space_Station Change of Command 🚀 @JonnyKimUSA returns home 🛫 Improving aviation safety 🔭 @NASAWebb discovers super-Earth’s atmosphere Follow along! 💫

Webb detected the strongest evidence yet for an atmosphere on a rocky planet outside of our solar system! Findings suggest ultra-hot super-Earth TOI-561 b is surrounded by a thick blanket of gases above a global magma ocean. https://t.co/d6g3z4pnUr

LIVE: What can Earth's extreme environments tell us about the search for life on other worlds? Our NASA experts are taking your questions! #AskNASA about how their expeditions are preparing us to explore the Moon, Mars, and beyond.

Take a spin around a spiral galaxy! @ChandraXray, @NASAHubble, and @NASAWebb studied this galaxy with a black hole at its center that is twice as massive as the Milky Way’s. Notably, a million-mile-per-hour wind being driven from the black hole lights up the galaxy's center.

After 245 days in space and nearly 4,000 orbits around the planet, @JonnyKimUSA has concluded his mission on the @Space_Station, returning to Earth on Dec. 9. Kim's mission benefits life on Earth while helping advance our journey from the Moon to Mars: https://t.co/UkXmlgfJyG

Back from the @Space_Station! @JonnyKimUSA has exited his Soyuz capsule after touching down on Earth at 12:04am ET (0504 UTC), wrapping up eight months of scientific discovery in low Earth orbit.

LIVE: After departing from the @Space_Station at 8:41pm ET on Dec. 8 (0141 UTC Dec. 9), @JonnyKimUSA is returning to Earth aboard the Soyuz MS-27 spacecraft. Landing is targeted for 12:04am ET on Dec. 9 (0504 UTC).

LIVE: Following farewells from the @Space_Station and hatch closing, @JonnyKimUSA is departing from the orbital lab and returning to Earth. Undocking is set for 8:41pm ET (0141 UTC Dec. 9).

LIVE: After eight months on the @Space_Station, @JonnyKimUSA is getting ready to return to Earth. Join us as he gives his farewell remarks and climbs into the spacecraft to head home. Hatch closure is scheduled for 5:15pm ET (2215 UTC).

Snap, crackle, boom ⚡ Our Perseverance Mars rover recorded a long-suspected phenomena—electrical sparks and mini-sonic booms created by dust devils on Mars. Learn more about this discovery and what it means for our understanding of the Red Planet: https://t.co/k1YvAWNe9g

LIVE: Tune in for a change of command ceremony aboard the @Space_Station. Cosmonaut Sergey Ryzhikov, who will return to Earth later this month, is handing over command of the station to NASA's @AstroIronMike.

Dig, if you will, this starburst. This starburst galaxy in the constellation Columba (the Dove) was snapped by @NASAHubble and helps astronomers study interactions between gas, star clusters, and supernovae in galaxies. https://t.co/SvNDiOKory

Another week keeping America LEADING on the final frontier 🚀 🛰️ Roman Space Telescope fully assembled 🇺🇸 @America250 on the Artemis II rocket 🧬 Astronauts join deep-space health study ✈️ @NASA tech making U.S. skies safer Follow along for more!💫

We won another Emmy! At the 76th Technology & Engineering Emmy Awards, we received an Emmy Award for Excellence in Production Technology for our live broadcast coverage of the 2024 total solar eclipse. Read more: https://t.co/EO0D9tG60Y

Studying other worlds can start in unexpected places... right here on Earth. On Dec. 10, we're talking with NASA scientists who explore some of our planet's most extreme environments. Share your questions in advance using #AskNASA: https://t.co/WSPUE5xYUL

Supermoon 🤝 Sphere 🌑 We're sending off the last Supermoon of 2025 with something special. Using @NASA’s public domain lunar data, our team built a true-to-science Moon that’s lighting up the Las Vegas skyline

Look up at the Moon! The last full moon of 2025 reaches its peak on Thursday, Dec. 4. This month's full moon is also a supermoon—meaning that it will appear slightly bigger and brighter than usual. Check out our Daily Moon Guide to learn more: https://t.co/cyRQZGZdAW

BREAKING: @NASA has selected two science instruments, designed for #Artemis IV astronauts to set up on the lunar surface, that will advance space exploration. ⬇️ 🔗: https://t.co/erYQtyFTxO
