They left miles-long craters in the Mid-Atlantic Chesapeake Bay and Siberia: the fourth- and fifth-largest asteroid craters on Earth. But what happened after they hit is puzzling to scientists ...
Scientists at one point projected it had about a 3% chance of hitting Earth in 2032. 2024 YR4 is now expected to miss Earth and "no longer poses a significant threat," according to a recent ...
Geologists believe that objects up to 450ft in diameter hit Earth every 100 to 300 years (Alamy) ... The craft and its cargo will remain in the asteroid's orbit for 100 days, and scientists ...
An asteroid first spotted in December has a 1.2% chance of hitting Earth in 2032. Scientists are tracking the space rock to learn more about its size and trajectory.
Artist's impression of the asteroid slamming into tropical, shallow seas of the sulfur-rich Yucatán Peninsula in what is today Southeast Mexico. [13] The aftermath of the asteroid collision, which occurred approximately 66 million years ago, is believed to have caused the mass extinction of non-avian dinosaurs and many other species on Earth.

Scientists say the risk of it making contact with Earth is remote — with NASA giving it as high as a 3.1% chance before reducing its estimate to 0.28%, and the European agency putting it at 0.16 ...

Luis Walter Alvarez, left, and his son Walter, right, at the K–T Boundary in Gubbio, Italy, 1981. The Alvarez hypothesis posits that the mass extinction of the non-avian dinosaurs and many other living things during the Cretaceous–Paleogene extinction event was caused by the impact of a large asteroid on the Earth.
