Nearly 20 years ago, astronomers observed a massive cloud of fine dust particles around a young star located just 63 light-years away from Earth. In recent observations from the Webb Space Telescope, however, the dust cloud had mysteriously vanished.
In about five years’ time, a potentially hazardous asteroid will swing by Earth at an eerily close distance of less than 20,000 miles (32,000 kilometers). During this rare encounter, Apophis will be ten times closer to Earth than the Moon and scientists want to take full advantage of its visit.
For nearly a decade, a near-Earth asteroid named Kamo’oalewa has invoked speculation over how it came to orbit the Sun in total synchrony with Earth as though it shares some special relationship with our planet. A new study of the oddball may have pinpointed where it came from: a young impact crater on the far side of…

After opening up that stubborn sample canister, NASA was finally able to weigh the full amount of asteroid bits snagged by its spacecraft more than three years ago. As it turns out, there is plenty of space rock that made its way to Earth.
After months of frustration, NASA finally got the Bennu asteroid sample container open in January, revealing the large amounts of asteroid scooped up by the OSIRIS-REx spacecraft.
Asteroid 99942 Apophis is fast approaching our home planet for an uncomfortably close encounter in 2029. In order to prepare for the rare event, NASA is calling for ideas for low cost missions to rendezvous with Apophis, but the space agency already has a pair of asteroid probes ready to take on the task.

Fresh off of its first asteroid encounter that revealed a bonus space rock, Lucy is now ready for the big leagues. The NASA spacecraft began maneuvering its way to Jupiter’s Trojan asteroids, traveling to a farther orbit in deep space in order to reach the Jovian system.
