Webb Zooms In on Building-Sized Asteroid Once Feared to Hit Earth – And It’s Stranger Than Expected NASA’s James Webb Space Telescope took a close look at asteroid 2024 YR4, which was once thought to be on a potential collision course with Earth. Although that threat has since been ruled out, researchers...

4/7 Webb's thermal data showed surprising properties unlike those seen in larger asteroids. The rock heats up and cools down differently, likely because it spins rapidly and its surface is "dominated by rocks that are maybe fist-sized or larger."

James Webb telescope takes emergency look at 'city-killer' asteroid 2024 YR4 ahead of close encounter in 2032 The James Webb Space Telescope has taken its first look at the near-Earth asteroid 2024 YR4 before a perilous close approach in 2032. The telescope confirmed Earth is safe, but the moon may still be in...

'That's Zero Folks!': Asteroid 2024 YR4 is no longer a hazard The likelihood of asteroid 2024 YR4 hitting Earth in 2032 rose and fell last week. NASA's impact odds are now so slim that the asteroid is no longer a hazard on the Torino asteroid scale.

Asteroid YR4 impact odds plummet as NASA changes threat level of 'city-killer' NASA has been changing the odds of asteroid 2024 YR4 hitting Earth in recent days, but the latest shift significantly downgrades the asteroid's threat level and makes a moon strike more likely.

🌑 The boulder analysis across four rubble-pile asteroids reveals consistent internal friction angles (~31.8°), despite differing asteroid compositions and sizes. This suggests shared physical processes shaping these bodies in our solar system! #AsteroidScience
