NASA's Dawn Mission Unveils Insights into Vesta’s Mysterious Gullies Using Lab Simulations
NASA’s Dawn mission to the asteroid Vesta revealed mysterious gullies on its surface. New lab experiments, simulating Vesta's harsh vacuum conditions, suggest that liquid water, possibly briny, could have flowed briefly and carved these channels. These findings challenge existing theories about liquid stability on airless bodies and provide insig...

Meteoroid Trails Could Help Detect Potentially Hazardous Comets Years in Advance
Meteoroid trails from long-period comets could provide early warnings of potentially dangerous comets near Earth, giving planetary scientists time to prepare. By studying these trails, scientists can track the paths of rarely visible comets that could pose a risk of impact, helping prevent catastrophic events. With the upcoming Vera C. Rubin Observ...

Taurid Meteor Stream Unlikely to Contain Dangerous Asteroids, New Study Suggests
A recent study led by Quanzhi Ye, an astronomer at the University of Maryland, reveals that the Taurid Meteoroid Complex, a debris stream linked to past Earth impacts, poses less danger than previously thought. Ye's team found fewer large asteroids in the stream, reducing the risk of a catastrophic collision with Earth. While these findings offer r...

Asteroid Bennu's Boulders Act as 'Body Armour' Against Small Meteoroids, Say Researchers
Scientists think that the boulders on the surface of Asteroid Bennu might be acting as a shield against meteoroids. When a meteoroid collides with Bennu, which is a rubber-pile asteroid formed from a much bigger asteroid, it ends up fracturing, chipping, or breaking apart the boulders. Impactors also create smaller craters on Bennu due to the boul...

NASA Says Tiny Meteoroid Struck James Webb Space Telescope, Knocked Gold-Plated Mirror Out of Alignment
A tiny meteoroid struck the newly deployed James Webb Space Telescope in May, knocking one of its gold-plated mirrors out of alignment but not changing the orbiting observatory's schedule to become fully operational shortly, says NASA.

NASA's Moon Orbiter Camera Survived Meteoroid Hit
The camera system aboard NASA's Moon orbiting spacecraft survived a hit by a tiny meteoroid in 2014 which was travelling much faster than a speeding bullet, the US space agency said today.

Meteoroid impact triggers bright flash on the moon
An automated telescope monitoring the moon has captured images of an 88-pound (40 kg) rock slamming into the lunar surface, creating a bright flash of light, NASA scientists said on Friday.
