The Asteroid Terrestrial-impact Last Alert System — a global network of telescopes funded by NASA to find Earth-threatening objects — spotted the asteroid 2024 YR4 in December

The newly discovered asteroid 2024 YR4 is thought to be large enough to wipe out a city and has triggered global defence plans

A newly identified asteroid, measuring between 40 and 100 metres wide, has been placed at the top of the asteroid risk list.

NASA’s two stuck astronauts took their first spacewalk together Thursday, exiting the International Space Station almost eight months after moving in. Commander Suni Williams and Butch Wilmore removed a broken antenna and wiped the station’s exterior for evidence of any microbes that might still be alive after launching

NASA astronauts Butch Wilmore and Suni Williams flew to the ISS in the summer of 2024 for a routine eight-day test mission. However, due to problems with the propulsion system of Boeing’s Starliner capsule,

Rock and dust samples from the Bennu asteroid contain molecules that are the "key to life" on Earth, NASA officials announced on Wednesday.

All forms of Earth life have specific chemicals in their makeup, such as amino acids and sugars. Scientists have known that asteroids hold molecules believed to be the precursors to these chemicals. By studying the Bennu samples, they hope to gain more insight into how these ingredients could have evolved.
