NASA was “completely wrong” about the asteroid Bennu
It wasn’t until landing on the asteroid Bennu that NASA learned its surface was more like a plastic ball pit than the relatively solid moon.
The cosmos can kill us in many ways. But the James Webb Space Telescope can help save us
Asteroid strikes, supernova explosions, and gamma-ray bursts are just a few of the ways the cosmos can kill us.
This is the damage a tiny speck of space debris can do at 15,000mph
A crater 5 inches deep was caused by something about the size and weight of an eraser on the end of a pencil.
What happens if the Solar System’s largest comet collides with Earth?
The asteroid that caused the last mass extinction 65 million years ago was only 5 kilometers across — tiny compared to this one.
We have a new way to hunt for potentially hazardous asteroids
To help protect Earth from potentially hazardous asteroids, astronomers developed an algorithm to look for them in existing datasets.
China is going to try to move an asteroid
As part of its new planetary defense strategy, the China National Space Administration is going to launch a mission to redirect an asteroid.
