How can you see what can’t be seen? By listening.

@NASAInSight spent four years listening closely to Mars with its super-sensitive seismometer, and a new study of two “marsquakes” is giving the clearest look yet at the Red Planet’s core. Read more: go.nasa.gov/3L3XYeS

218 light-years away in the constellation Lyra, are two planets unlike any in our solar system. Astronomers think that a significant fraction of their volume should be made of something lighter than rock but heavier than hydrogen or helium: water. go.nasa.gov/41BRXNC

we used to have braille coloring books we liked to color in, but we had to leave them behind when we moved because they weren't technically ours. would love to get some more, and some crayons, would totally let the littles color again.

As fires burned across eastern Kansas in March and April, they left a patchwork of scars that can be seen from space.

Happy #WorldPenguinDay! 🐧

This Hubble view of interacting galaxies, known as Arp 142, resembles a penguin with its egg.

In reality, this galactic pair reside about 326 million light-years away in the southern constellation Hydra: go.nasa.gov/3V1SHsV

33 years later, Hubble continues to explore and inspire!

@NASAHubble was deployed by Space Shuttle Discovery #OTD in 1990, becoming one of the notable success stories in NASA's history!

What's your favorite @NASAHubble image? bit.ly/3NauIG3

Launched 33 years ago today, the orbiting telescope captured this image of a nebula where stars are born -- 960 light-years away. go.nasa.gov/3VizSlr

So hard to choose! Light Saber or Monocerotis? Saturn is, of course, pretty spectacular.


Other planets experience auroras as well. This view of aurora on Jupiter combines two images from the Hubble Space Telescope, which launched 33 years ago today. Happy birthday, @NASAHubble! 🎂🔭 go.nasa.gov/3n3k3C8

My first guess would be New Orleans area? I see a whole lot of water that must be pretty shallow if it also has deltas fanning out from the outflows.

The Okavango inland delta in Botswana. It floods seasonally, and becomes a vast temporary wetland.


5,338! That's how many planets we've confirmed beyond our solar system, six more worlds than we knew of last week. We are in an age of discovery✨ exoplanets.nasa.gov/discovery

I really feel like what you're calling "terrestrial" should really be called "Class M". #StarTrek
in reply to NASA

you have confirmed planets by actual sightings, or speculate/assume that observed aberrations in distant stars are planets?


Picard's final season often struggled with not-quite-right characterization, an obsession with twists, and a focus on Picard to the exclusion of other characters—but in its last four episodes, the show finally delivered on its original promise.

yeah I like that part. Just not really the times when he is really inept about sending his crewmates the heads of his enemies. By the end of TNG, he had become really solid about interfacing with humans, and it's weird to see him lose that.


When particles from @NASASun meet @NASAEarth, sparks really fly. Yesterday a coronal mass ejection – particles ejected from the Sun – reached Earth's magnetic field, leading to spectacular auroras. Did you catch them? More about these geomagnetic storms: go.nasa.gov/3HaVKJg

This is shaping up to be a giant cluster…of galaxies.

These 7 spotlighted galaxies form a protocluster so far away, its light took ~13 billion years to reach us. Webb scientists predict it may grow into one of the largest, densest galaxy clusters known: go.nasa.gov/3V5UEnZ

That's great! But, how many species has NASA saved from extinction?


❄️ The Sierra Nevada received a historic 200 percent or more of expected precipitation this water year. This boom was caused by eleven moderate-strength atmospheric rivers, which is twice the average number.

Thank you! I'd lost count of how many atmospheric rivers we had. 🤔

The mountainous islands disrupt the flow of air, which can have a ripple-like effect on the clouds. An astronaut aboard the @Space_Station captured this image earlier this year.
