A few months ago, an asteroid created quite a buzz. At one point, asteroid 2024 YR4 had a 3.1% chance of hitting Earth, creating plenty of headlines about its potential impact. The threat is all ...

(CNN) — It’s a long-standing debate in paleontology: Were dinosaurs thriving when an asteroid hit Earth one fateful spring day 66 million years ago, or were they already on their way out ...

A new study challenges the belief that dinosaurs were declining before the asteroid impact that ended their reign. Analysing 18 million years of fossil data, researchers argue that apparent drops ...

This is a still from an animation showing asteroid 2024 YR4 as it passes by Earth and heads toward its potential impact with the Moon. This 3D shape of the asteroid was determined from data ...

A team of astronomers used the Gemini South Observatory in Chile to observe asteroid 2024 YR4 in multiple wavelengths as it zoomed away from Earth in February, barely 1 1/2 months after its discovery.

"It's been a subject of debate for more than 30 years—were dinosaurs doomed and already on their way out before the asteroid hit?" said Dean, according to SciTechDaily. The study, published in ...

That means there's a better than 96 percent chance it's going to miss the Moon, but if it did hit the Moon, it really would be pretty spectacular!” The asteroid is estimated to be 53 and 67 ...

Dinosaurs were not in decline before the asteroid hit, instead poor fossilisation conditions and unexposed late Cretaceous rock layers mean they're either not preserved or hard to find ...

However, there remains a risk for the moon — not that the asteroid would significantly damage the moon even if it does hit. For the new study, researchers captured images of the space rock at ...

Earth Is Safe From Menacing Asteroid—but Our Moon Might Take the Hit The Moon, however, is still not safe from the flying space rock. NASA’s Center for Near Earth Object Studies recently ...
