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 launched from California changed not just the orbit of Dimorphos, the asteroid it hit, but the larger Didymos' path around the sun.

One of the anticipated dangers from outer space is that a meteor could crash into earth, and cause mass extinction. It had happened once 65 million years ...

A 1,300-pound NASA satellite is expected to crash through Earth's atmosphere March 10, 2026, with some of the spacecraft possibly surviving re-entry.

New observations have ruled out the chances of an asteroid hitting the moon in 2032, according to scientists using the James Webb Space Telescope.

A bright new lunar crater detected in spacecraft images shows that asteroid impacts continue to reshape the Moon’s surface today. The Moon’s familiar surface tells a story of both ancient violence and ...

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 ...

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

New observations from NASA's James Webb Space Telescope confirm asteroid 2024 YR4 will not hit the moon in 2032.
