A massive comet trail may have caused climate upheaval on Earth more than 12,000 years ago, sparking the Younger Dryas.

Astronomers have discovered an object at the edge of the solar system that is locked in a strange rhythmic dance with the ice giant Neptune.

Complex organic molecules found floating around a distant protostar could mean that space is far richer in life's precursors than scientists assumed.

Debris released from the asteroid Dimorphos during NASA's DART mission has a higher momentum and less random distribution than expected, which "changes the physics we need to consider when planning these types of missions," researchers say.

A newly discovered object, dubbed A11pl3Z, appears to be moving too fast and straight to have originated in the solar system. If confirmed, it will be the third interstellar visitor ever spotted.

There is currently a 4.3% chance that the giant space rock 2024 YR4 will hit the moon in seven years. If this does happen, debris from the nuclear bomb-like impact could trigger a "spectacular" meteor shower that will endanger Earth-orbiting satellites.

A new image released by China's space agency offers the first glimpse at the Tianwen 2 spacecraft, which is en route to collect samples from one of Earth's "quasi-moons". The photo shows some surprising similarities with a current NASA probe.

Vesta, thought to be the second-largest asteroid in the solar system, could be a piece of an ancient, unknown planet, a new study hints.

The dinosaurs were not in decline before the asteroid hit, a new study finds. Instead, poor fossilization conditions and unexposed late Cretaceous rock layers mean they're either not preserved or hard to find.

NASA has released the Lucy spacecraft's first close-up images of asteroid Donaldjohanson, revealing a peanut-shaped rock that could shed light on how planets formed in our solar system.
