The night lizards may have been the only terrestrial vertebrates that survived in the region of the asteroid impact 66 ...

The next big space threat isn't to Earth. It's to the Moon.

A new study published on arXiv suggests a potentially catastrophic scenario for Earth’s satellites and space infrastructure ...

Thirty minutes. That's all it took, 66 million years ago, to put the future on track for you to be reading this. Had the Manhattan-Island-size asteroid that crashed into the Gulf of Mexico arrived ...

The odds that a potentially destructive asteroid will collide with Earth in 2032 have increased once again, NASA says, but ...

Two weeks ago, when Ars first wrote about the asteroid, designated 2024 YR4, NASA's Center for Near Earth Object Studies estimated a 1.9 percent chance of an impact with Earth in 2032.

Its cumulative impact probability is currently 1-in-63, or a 1.58% chance of an impact (which, it should be stressed, means a 98.4% chance the asteroid misses Earth).

In 1980, the first paper to suggest that an asteroid killed the dinosaurs came out, under the pleasingly dramatic title "Extraterrestrial Cause for the Cretaceous-Tertiary Extinction".

The iridium-rich layer is known as the K/Pg boundary, and a similar metal in the same rocks has provided the geological fingerprint for where the asteroid came from. The key metal is ruthenium.

Around 4 billion years ago, an asteroid hit the Jupiter moon Ganymede. Now, a Kobe University researcher has realized that the solar system's biggest moon's axis has shifted as a result of the ...

Slower moving particles blasted out by the DART impact on the asteroid Dimorphos could create meteor showers on Mars — but it's unlikely they'll cause meteor showers over Earth.
