Scientists discover binary asteroids near Earth can trade rocks and dust through slow collisions, revealing clues about asteroid evolution.

NASA’s DART mission proved that a spacecraft can nudge an asteroid system in space, offering a real test of planetary defense. NASA’s DART (Double Asteroid Redirection Test) spacecraft changed the ...

NASA's DART mission didn’t just change the orbit of Dimorphos, the asteroid it hit. It changed the orbit of the larger ...

New images from NASA's DART asteroid-smashing mission show space rocks exchanging material in a slow process that reshapes their surfaces over millions of years.

In 2020, astronomers discovered a violent cosmic event that has led them to rethink how extreme pairs of astronomical objects form. These pairs are capable of producing powerful cosmic collisions.

NASA’s DART mission changed the Dimorphos' asteroid orbit around the Sun, proving spacecraft impacts could help defend Earth.

In 2022, NASA hit Dimorphos with a spacecraft. But looking back through the data, astronomers believe they have found evidence of an impact event prior to the big test.

New ALMA and JWST observations reveal why Wolf–Rayet star WR 112 produces tiny dust grains, showing a bimodal grain distribution in its binary system.

Bright streaks on a small asteroid moon looked, at first, like a camera problem. They were faint, fan-shaped, and easy to ...

Findings support kinetic impact technique for planetary defense.

Images from NASA’s DART mission revealed the first direct evidence that asteroids in a binary system can exchange rocks and dust. Slow moving debris from the asteroid Didymos appears to have struck ...
