@NASA Mars is round! Or, round-ish. Like Earth, Mars isn't a perfect sphere. This video, made from images taken using a @NASAJPL camera on @NASAHubble, shows Mars rotating.

@NASA Am I the only one that sees a gentle arc when I look at the horizon?

@NASA Clearly he isn't, but the dude looks the type to preach the flat earth thought. It is a mystery it is a thought at all. Just looking at the horizon from the shore will show the curvature.

Space exploration confirms it: Earth is the best planet. Our planet's resources are finite, but space offers endless possibilities. We can guarantee a sustainable future by sourcing what we need from space and moving polluting industries off Earth. Join the mission to protect our planet for the benefit of Earth, our blue origin.

“When you look at the Earth from space, you realize that our planet is a beautiful, interconnected system. We are all in this together.” - Mae Jemison, Space Shuttle NASA astronaut This time-lapse taken aboard the International Space Station shows a blanket of stars surrounding our Earth. The view is one that is known to create a moment of pause in appreciation of the beauty of our shared home. #WorldViewWednesday

This new NASA mission will get a whole new look at our home in space. 👀 The Interstellar Mapping and Acceleration Probe, or IMAP, will chart our heliosphere, the giant bubble encasing our solar system. The heliosphere is like Earth’s house in space: It shelters our planet from interstellar radiation and helps keep it cozy, safe, and suitable for living things — like us! 🌱🌎 With a comprehensive suite of 10 instruments, IMAP will reveal our heliosphere with 30X better resolution than we’ve ever had before, helping us understand how our Sun creates and maintains our protective bubble in space. The launch window opens at 7:32 am ET on Sept. 23, 2025. More details here:

When it comes to space science, astronauts discover bubbles don’t rise, things float away, and Earth-based lab tools don’t always work the same way. A NASA scientist explains how we study life, chemistry, and physics in orbit. More...

If you close your eyes aboard a spaceship, you sometimes see flashes of light, as radiation/high-energy particles hit your optic nerve (on Earth the magnetic field protects us). It messes with our computers too - NASA is testing new lunar tech (video: 2001 A Space Odyssey)

From the surface of the Moon, Earth appears as a bright and beautiful sphere our home floating in the vast darkness of space. Every ocean, continent, and form exists on that distant blue world. The contrast between the Moon's silent, grey landscape and Earth's vibrant colors makes this view truly powerful. It reminds us how special and unique our planet is. Standing on another world and looking back at Earth changes perspective everything we know is contained in that small glowing sphere. A distant view... but still home
