Earth is our home. 💚

On #EarthDay and every day, we’re learning more about our world and how it’s changing – giving us a deeper appreciation for the planet we call home.

Celebrate with us: go.nasa.gov/3mZmeXx
#NASAEarth



We love Earth so much, we're looking for planets like it!
#NASAExoplanets


Of all the planets in the galaxy, we're living on the best one for us and everything we love. Happy #EarthDay, Earthlings💚

This week at NASA, we marked the Ingenuity #MarsHelicopter's 50th flight on the Red Planet, the planet-hunting satellite TESS entered its fifth year, and we celebrated our favorite planet—Earth!

Happy #EarthDay 🌍

From the tallest peaks to ocean depths, from arid deserts to lush forests, we observe our home from a unique perspective. Learn about the activities all around NASA, and about the picture that kicked off this celebration of our planet: go.nasa.gov/41yzVvI

Thank you for reminding us how:

Beautiful our planet is

And the fragility of what we have



What was it like when Apollo 8 astronaut Bill Anders saw Earth rise over the Moon’s horizon in 1968?

He reflects with Dr. Kate Calvin, NASA senior climate advisor and chief scientist, on taking the famous photo helped humanity "discover" Earth. go.nasa.gov/43QKQCr

"Oddly enough the overriding sensation I got looking at the Earth was, My God that little thing is so fragile out there."

— Michael Collins, Apollo 11 astronaut

for the vision-impaired, the photo shows the planet earth as seen from space.


"That beautiful, warm, living object looked so fragile, so delicate, that if you touched it with a finger it would crumble and fall apart. Seeing this has to change a man."

— James B. Irwin, Apollo 15 astronaut

After a cargo return and a Russian spacewalk earlier this week, we celebrate the ways the space station helps us understand and care for our planet on a special #EarthDay edition of #SpaceToGround. 🌏🛰️

"Circling the Earth in my orbital spaceship, I marveled at the beauty of our planet. People of the world, let us safeguard and enhance this beauty, and not destroy it."

— Yuri Gagarin, Vostok 1 cosmonaut, first human in space

"Every single part of the Earth reacts with every other part. It’s one thing. … If I could get every Earthling to do one circle of the Earth, I think things would run a little differently."

— Karen Nyberg, STS-124, and Expedition 36/37 astronaut

NASA why do you not add Alt-Text to your images? I would love to boost these and engage with them, but you gotta do the alt-text thing.

oh please, not this "send people into space to save the planet" thing again. <eyeroll>

New view: I’m getting a peek into Belva, a crater within a crater. It’s ~0.6 miles (1 km) wide, and sits on top of this fan of sediments that a river carried into the much bigger Jezero Crater long ago. A few mysteries to explore here before I roll on: go.nasa.gov/3GWA8jZ

There's strong evidence – including a radioactive type of iron – that supernovae occurred close to Earth between ~2m-8 million years ago. A new study shows how X-rays from such stellar explosions could threaten any life on surrounding planets for decades. go.nasa.gov/3op5LvX
#NASAExoplanets


Space telescopes like @chandraxray and NuSTAR were used for the supernovae study because they observe the universe in high energy X-rays. X-ray views help us see beyond visible light! go.nasa.gov/3omAxWi
