The asteroid impact that wiped out the dinosaurs didn’t keep life down for long. New research shows that microscopic plankton began evolving into new species within just a few thousand years—and ...

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 ...

Astronomers have collected evidence of a violent collision between two planets in a distant star system. The first clues of this cataclysmic event came when a rather boring star began behaving very ...

Astronomers say a distant, sunlike star shows signs of a catastrophic planet-on-planet crash that may mirror the ancient impact that formed Earth's moon.

When people think of asteroids, they tend to picture rare, civilization-ending impacts like those depicted in movies such as "Armageddon." In reality, the asteroids most likely to affect modern ...

According to the space agency's tracking, the rock is hurtling through space at more than 21,500 miles per hour.

An unusual flickering of a young F-type star called Gaia20ehk and an expanding cloud of dust around it suggest that a catastrophic planetary crash unfolded in real time, offering a rare glimpse of the ...

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

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

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

An asteroid, previously used by NASA for a planetary defence test, has been successfully shifted onto a slightly altered path ...
