Falling Asleep with the Universe

@NASAHubble This is exactly why we look up! 🌌 It’s humbling to think that even when we aren't looking for something specific, the universe finds a way to show us its most violent and beautiful secrets. Hubble still proving it's the GOAT.

Sometimes, the best science happens on accident. A team using Hubble studied a comet (not even their first-choice target!) and realized they were witnessing it in the act of breaking apart. Find out more about these ultra-rare observations: go.nasa.gov/4lUAdIl

@NASA_Johnson Who needs a four-leaf clover when you’ve got a front-row seat to the ultimate light show? 🍀 Nature’s own neon sign for St. Paddy’s Day! Absolutely breathtaking view from the ISS.

Forget the pot of gold, we found the whole sky glowing green. 💰🍀 Auroras form when energized particles from the Sun collide with gases in Earth’s upper atmosphere, creating waves of color that ripple across the night side of the planet. From 250 miles above Earth aboard the International @Space_Station, astronauts can see these shimmering curtains stretch for hundreds of miles. A perfect view for St. Patrick’s Day!

@NASA @Astro_ChrisW @Astro_Jessica @Space_Station Nothing beats the view from the 'office' today! 👨‍🚀 Huge respect to Chris and Jessica for taking on this 6.5-hour marathon in the vacuum of space. Safe travels outside, team! #SpaceWalk #NASA

LIVE: Tune in to watch @Astro_ChrisW and @Astro_Jessica go for a spacewalk! Our astronauts are scheduled to step outside the @Space_Station at about 8am ET (1200 UTC) and work for about six-and-a-half hours. twitter.com/i/broadcasts/1…

@SpaceX Raptor 3 startup on Pad 2 is a massive milestone! The transition to V3 is where things get really serious for Mars. Can’t wait to see all 33 engines lighting up the Texas sky soon. The pace of iteration at Starbase is unmatched!

Initial Super Heavy V3 and Starbase Pad 2 activation campaign complete, wrapping up several days of testing that loaded cryogenic fuel and oxidizer on a V3 vehicle for the first time. While the 10-engine static fire ended early due to a ground-side issue, we saw successful startup on all installed Raptor 3 engines. Next up: preparing the booster for a 33-engine static fire

@NASASpaceAlerts Nearly 6 feet and 7 tons? Sounds like my morning coffee trying to hit my system at 45,000 mph. Imagine seeing a literal space rock casually cruising over Lake Erie in broad daylight!

#MeteorSighting: A very bright daylight fireball was observed by witnesses from the northeast U.S. and Canada this morning, March 17. An analysis of currently available data places first visibility of the meteor above Lake Erie. The fireball - caused by a small asteroid nearly 6 feet in diameter and weighing about 7 tons - moved southeast at 45,000 mph before fragmenting over Valley City. The fragments continued on to the south, producing meteorites in the vicinity of Medina County, Ohio. 🔗 go.nasa.gov/4bcMwMg Eyewitness accounts supplied by the American Meteor Society

With all that chaos, black holes, and expansion, you’d think things would’ve crumbled by now. Tonight, we’re diving into the invisible glue holding the cosmos together. #Cosmos #Space #Podcast #DeepThoughts youtu.be/wTAkdwRFVkA

@airandspace @NASAWebb Building a sun-skimming spacecraft out of 'spare parts' is the ultimate engineering flex. The Parker Solar Probe is legendary, and having the JWST Pathfinder there really completes the 'Golden Age of Discovery' vibe. Incredible additions!

Now on display at Air and Space: 🌌 James Webb Space Telescope Pathfinder, a full-scale engineering model used by @nasawebb for critical testing in development of the spacecraft ☀️ Parker Solar Probe full-scale model built primarily out of spare parts and back-ups from the spacecraft that has flown through the Sun’s corona

@NASAUniverse Love this! Proof that while Fermi is busy tracking gamma-ray bursts, the team is busy mastering the 'crust-mos.' It’s amazing how a little math and a lot of heat can explain everything from a perfect lattice to a black hole. Keep serving those cosmic slices!

Members of our Fermi mission team bake in their free time! While Fermi studies gamma-rays, not blueberries, it serves us a slice of the universe that includes some of its most extreme environments and events. What can pi(e) can teach us about the cosmos? go.nasa.gov/4lrLMX9

@NASAHubble @NASAWebb Seeing Hubble and Webb join forces is the ultimate cosmic crossover! 25 million light-years away and it still looks like I could reach out and touch it. The detail in the 'Pinwheel' is absolutely breathtaking.

Let’s get to the heart of it. 🧡 This new image from Hubble and @NASAWebb takes a closer look at the core of Messier 101, also known as the Pinwheel Galaxy. At 25 million light-years away, M101 is one of the closest “face-on” spiral galaxies to us: go.nasa.gov/4lydce2

@Space_Station 8 months in the void and a perfect undocking right on schedule. It’s easy to forget how incredible these routine milestones actually are. Safe travels back, Progress 92!

After an eight-month stay at the space station, the unpiloted Roscosmos Progress 92 spacecraft undocked from the station’s Poisk module at 9:24am ET today. nasa.gov/blogs/spacesta…

@NASAhistory 41 feet for a rocket, but a giant leap for humanity. It’s wild to think that this 2.5-second flight in a cabbage patch paved the way for us to reach the Moon and beyond. Happy 100th to the spark that started it all!

A 2.5-second rocket flight that heralded decades of discovery in space! Today marks 100 years since the first successful test of a liquid-fueled rocket. Robert H. Goddard's achievement would have appeared unimpressive by most measures: His rocket flew just 41 feet in the air, landing in a nearby cabbage patch. Liquid-propelled rocketry has been the backbone of spaceflight ever since. 📷 by Esther Goddard on March 16, 1926 (Clark University Archive)

@SpaceX @Starlink The pace is absolutely insane! 🚀 We’re witnessing history becoming a daily routine. Reusing boosters 30+ times is the peak of engineering. Amazing work by the @SpaceX team!

@NASAScience_ This is the power of Citizen Science! It’s so inspiring to see how professional researchers and volunteer astronomers can team up to track planetary defense. Science truly belongs to everyone.

NASA used a spacecraft to hit an asteroid. Now scientists have discovered the impact altered the orbit of that entire asteroid system around the Sun. Discover how they measured this tiny change with help from volunteer astronomers around the world: go.nasa.gov/4uqwl5w

@NASAHubble Cosmic jewelry at its absolute finest! It’s mind-blowing to think that the 'jewels' we see are actually dense knots of gas from a dying star. Hubble never fails to remind us how beautiful the universe's transformations are.

Decked out in stars! The Necklace Nebula glows brightly in this Hubble image. These are actually the remains of a dying, Sun-like star, with a ring that consists of dense knots of gas that look like jewels on a necklace. Learn more for #JewelDay: go.nasa.gov/3P6yC5S

@NASAHubble The Messier Marathon is easily the best time of the year for space nerds! 🚀 Hubble always delivers the gold standard. I’m personally hoping for a fresh look at M31 or M42—which Messier object are you guys most excited to see?

Welcome to Hubble's Messier Marathon 2026! This annual event encourages astronomers to target cosmic objects from the Messier catalog, compiled by French astronomer Charles Messier in the 1700s. We're sharing new Hubble images of Messier objects through next weekend ⬇️

@NASA Eight minutes to space, ten days to make history. I’m particularly curious about the 'proximity operations'—testing how Orion handles close-range maneuvers. Which part of the 10-day flight plan do you think is the most critical for the success of Artemis III? Let's discuss!

About eight minutes after Artemis II lifts off, the Orion spacecraft and the astronauts aboard will be in space. But what happens after that? Check out the Artemis II daily agenda to learn about the activities of the 10-day lunar mission: go.nasa.gov/3NBxpmr

@SpaceX @Starlink 29 more satellites, millions more connections. It’s not just about the launch; it’s about closing the digital divide one Falcon 9 at a time. The future of global connectivity is looking brighter than ever!
