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 September 2022, a spacecraft the size of a refrigerator slammed into a small asteroid at nearly 24,000 kilometers per hour (15,000 miles per hour). The collision was deliberate and the asteroid ...

The mission without a doubt proves that we could deflect a hazardous asteroid away from Earth — so long as we discover it in ...

Studying the 2022 collision's effects can help scientists protect the Earth from celestial objects that might head toward us ...

In 2022, a NASA spacecraft intentionally barreled into the tiny asteroid Dimorphos during a planetary defense test. New observations show how it went.

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

A NASA defense spacecraft altered the pathway of two asteroids’ orbits around the sun, according to a new study. Research published in Science Advances on Frida ...

NASA/Johns Hopkins APL/Steve Gribben Around 15 percent of near-Earth asteroids have small moons, which suggests binary systems are fairly common. Many of the larger asteroid pairs have likely formed ...

The pair, millions of miles away, continues to pose no danger to Earth, and scientists say it will remain safely distant for at least the next century. But the experiment has already delivered ...

When NASA’s DART spacecraft deliberately crashed into the asteroid moonlet Dimorphos, it did more than change the asteroid’s local orbit — it slightly shifted the path of the entire asteroid pair ...
