Choose your own adventure! One galaxy, seen by @NASAHubble, is a wispy dream, in visible and ultraviolet light. The same galaxy, revealed by @NASAWebb, glows brightly against the black of space; the inner structure revealed in infrared... (Both. You can choose both.)

Yesterday we crashed into an asteroid (on purpose), so, what should we do today? How about welcome 84 new exoplanets into the known worlds? Most are gas giants or ice giants that might be ripe for followup. The number of confirmed exoplanets is now 5,171! exoplanets.nasa.gov/discovery/disc…
This one is for the dinosaurs! 🦖🦕 And the science! It was definitely for the science. And planetary defensetwitter.com/NASA/status/15…la
Psst... We're about to crash into an asteroid ON PURPOSE! Our #DARTMission’s DRACO camera updates in real time as it approaches asteroid Dimorphos for impact, 7 million miles (11 million km) away. And, don't worry! Earth is safe before, during and after. youtube.com/watch?v=-6Z1E0…
Today the #DARTMission will make history in a full-scale #PlanetaryDefense test when it intentionally impacts a non-threatening asteroid. 📺 Live coverage at 6pm EDT (2200 GMT):nasa.gov/liveB 💥 Impact at 7:14pm EDT 🛰 All about DART & asteroidsolarsystem.nasa.govm2lc

This is only a test – of planetary defense. @NASA's #DARTMission will crash into a non-hazardous asteroid to test deflection technology, should we ever discover a threat. Impact: 7:14pm ET (23:14 UTC). Watch our LIVE broadcast at 6pm ET: youtu.be/4RA8Tfa6Sck
When @NASA's #DARTMission rams into asteroid Dimorphos today, space & ground telescopes will be watching to gather all the science we can. One tiny spacecraft will provide us a front-row seat: LICIACube, which captured this view of Earth (and YOU) from 6.7M miles (11M km) away!
Planetary defense test?! We'll be watching! 3p PT/6p ET nasa.gov/live twitter.com/AsteroidWatch/…
Happy SUNday! Our star is perfect for Earth. A young planet 32 light-years away isn't so lucky. It lurks in a giant disk of dust and debris while its star ceaselessly blasts it with X-ray flares and other radiation. go.nasa.gov/3SpqiuN
Science makes our hearts pitter patter. Listen to the rapid beat of HD 31901, a Delta Scuti star in the southern constellation Lepus. The sound is the result of a month's worth of 55 pulsation patterns sped up 54,000 times. go.nasa.gov/2LlLwIS
X-ray light helps us study some of the most extreme objects (ahem), events and environments in the universe. @NASA's NuSTAR space telescope has been exploring our universe with its X-ray vision for more than a decade! go.nasa.gov/3Sps7b7
This boop is only a test 📣 @NASAA's#DARTMissionn will impact with Dimorphos, an asteroid moonlet that poses no threat to Earth. This is a planetary defense test to see if we can change the path of an asteroid. We'll be watching on Monday. Join us? More:go.nasa.gov/3Bx4YMrg0
Happy Friday, friends🔥 How about some flair? Posters, wallpapers and backgrounds are there for you atexoplanets.nasa.gov/travelf. Click ''get the poster'' and you're set. Take a guided tour with sound while you're there or see a 360° lava sea. We're all about options.k
One of the most extreme exoplanets, WASP-12b, is being stretched into a football shape by its star! @chandraxray's observations helped tell us more about this doomed world being eaten by its star. exoplanets.nasa.gov/exoplanet-cata… twitter.com/NASAUniverse/s…
Happy first day of fall/spring, depending on your hemisphere! Earth is so lucky to have seasons. Many exoplanets are tidally locked, meaning the same side always faces the star and the other side is locked in perpetual darkness. (Like our hearts?🖤 Maybe!)Exoplanets.nasa.govgL
What might an exoplanet with a ring system 200 times larger than Saturn's look like? So glad you asked. Imagine rings that would eclipse our Sun!
Let them ring! @NASAWebb has seen rings around Jupiter and Neptune, and, of course, Saturn is ringed (so is Uranus, btw). Good news for rings around cold, gas giant exoplanets! We know of an exoplanet candidate with rings ~200 times larger than Saturn's! go.nasa.gov/3UrCRHg
Enhance! @NASAWebb turned its infrared eye on Neptune and got the clearest images in decades of the ice giant's rings. The closeup is stunning, but so is the far-away view, showing our solar system's most distant planet and moons with galaxies far beyond. go.nasa.gov/3RXxoGq
A new super-Earth on the scene might be a water world. Its mass measurements are consistent with a deep ocean, though we can't be sure. It orbits a red star that's one of a pair; its sun's gravitational partner also is a red dwarf. go.nasa.gov/3dWUw97
To know planets, you need to understand stars, and X-ray vision allows us to look at stars' temperaments. Observations show they can settle down after fiery starts, boding well for planets and potential future habitability. go.nasa.gov/3UpNLxa
X-ray vision gave us some of the first key science about exoplanets and it continues to be an important tool. twitter.com/NASAUniverse/s…
Scientists checked in on Earth's planetary neighbor Mars with @NASAWebb and atmospheric readings reveal carbon dioxide, carbon monoxide and water. Reading the light like this is how we can now study planets *much* farther away.🤩 go.nasa.gov/3SbzeDgD8
Listen to a butterfly🦋@NASAHubblee's light data from the Butterfly Nebula sings when we convert it to sound! The nebula is played on strings and synthetic tones, while stars are represented by digital harp. A dying star never sounded so sweet.h

5,084! We know of more planets today than we did yesterday. Six more, in fact, including TOI-2193Ab, a gas giant exoplanet, 1,100 light-years from Earth. A ''year'' there, one orbit of its star, takes 2 days. go.nasa.gov/3RRPI3A
Science never stops! Our beloved Kepler Space Telescope retired in 2018, and we're still finding planets in its data. twitter.com/NASASolarSyste…
From the calcium in our bones to the iron in our blood, we really are made from starstuff. It's even in our DNA – carbon, hydrogen, oxygen, nitrogen and phosphorus were all forged in ancient stars and distributed throughout the universe to become planets, puppies and you!
Without clear, undeniable evidence, the search for life beyond Earth is a journey of many steps. We look for all kinds of clues – like biosignatures. Organics like oxygen, carbon and methane could indicate potential for, or past, life. go.nasa.gov/3QGwY5W
A good day for science is a good day for everyone! twitter.com/NASAUniverse/s…
One of humanity's most fundamental questions – are we alone in the universe – remains unanswered. We've found ingredients key to earthly life on other planets, but that's, literally, just the start. go.nasa.gov/3eLVF3A
You’ve seen the latest image or finding from Webb online, and you want to know: why can’t I find it on the official NASA account? Scientists may share Webb data as they receive it, but we’re following a more formal process. Let’s walk through it: blogs.nasa.gov/webb/2022/09/1…

Stars sculpt the universe.✨ A huge, oddly shaped stellar nursery called NGC 346 seems to be feeding star formation in a river-like motion of gas and stars. This spiral of starbirth (seen by @NASAHubble) is giving us a window into the early universe. go.nasa.gov/3S03QaL
When did a thermonuclear explosion destroy a neighboring white dwarf star? X-ray data (green, blue & purple) from @chandraxray and optical data from @NASAHubble (red & white) are helping us better understand this supernova's timeline of destruction. go.nasa.gov/3eCZwjj
Could water worlds be more common than we think? Study finds that some terrestrial planets could have water beneath the surface or hidden in rocks. bit.ly/3xiVCCC
Early in our solar system, there was no Moon. Scientists think it was created after a Mars-sized planet smashed into a young, molten Earth billions of years ago. go.nasa.gov/3RxAu3F
Just below stars' surfaces, hot gas rises, cools, and then sinks, where it heats again. This motion produces waves of changing pressure – sound waves. We can't hear them, but we can see them as subtle shifts in brightness. go.nasa.gov/3d002rb
Could one of the biggest puzzles in astrophysics be solved by reworking Albert Einstein’s theory of gravity? Maybe! Astronomers are digging into dark energy and the expansion of the universe. go.nasa.gov/3x9S99n
A brand new stamp features @NASAWebb along with an illustration of two lovely planets. You don't need to write, but we know someone out there would love to hear from you.💌go.nasa.gov/3BremlOE1
Queen Elizabeth II's reign spanned all of spaceflight, predating both Sputnik and Explorer 1. As we join the planet in marking her passing, we are moved by the curiosity Her Royal Highness showed our explorers over the years.

#OTD in 2005 and 2006, @NASA's Cassini spacecraft made a close flyby of Saturn and its moon Titan. Finding an exoplanet like Titan, with lakes, seas and thick atmosphere might be like finding a world early in development, with ingredients key to life. go.nasa.gov/2DyO5Wd
Studying stellar waves can help us understand conditions for nearby planets. Our own Sun has thousands of these waves bouncing around at any given moment! go.nasa.gov/2T014Dp
We can't hear it, but there is a nonstop symphony in space as sound waves bounce around stars🎵 The biggest stars make the lowest, deepest sounds, like tubas. Small stars have high-pitched voices, like flutes.go.nasa.gov/2T014DpYD
Discovery Alert! More than 1,200 light-years away, a planet about the size of Jupiter orbits its star in 8 days. It is one of the 17 exoplanets that joined the known worlds last week. The total number of confirmed exoplanets is 5,084 -- for now! exoplanets.nasa.gov/discovery/disc…
Before they were stars✨ This new @NASAWebb image reveals secrets of the Tarantula Nebula: thousands of never before seen baby stars and forming protostars. The nebula, 161,000 light-years away, is home to the hottest, most massive stars known. go.nasa.gov/3RD7Ldt
Listen to the Carina Nebula sing 🎶@NASAWebbb's images are full of science (star birth, dense gas and dust, etc.), but what if we gave them sound? Do you experience them in a new way? We hope so — because they're *yours*. Space is for everyone.v

Now that we've seen @NASAWebb's first direct image, let's turn up the volume and dance to its science! The sounds were chosen to reflect Webb's findings on an exoplanet called WASP-96 b (listen for water in this sonic data interpretation). go.nasa.gov/3AYc3qq
