Paul Wiegert, a Western physics and astronomy professor, shares insights on asteroid 2024 YR4 and the likelihood it will hit Earth or the Moon.

It ultimately was successful, with NASA correctly predicting that it is possible to redirect celestial objects. The asteroid known as Dimorphos was approximately the size of the Great Pyramid of Giza, ...

When a vending-machine-sized spacecraft hit Dimorphos in 2022, planetary defense experts anticipated an easy test of kinetic ...

In 2022, NASA rammed a spacecraft into an asteroid to see if it could alter its orbital period around its parent asteroid. The mission, dubbed the Double Asteroid Redirection Test (DART), aimed to ...

How does a planetary defense mission intended to push an asteroid off course manage to release a torrent of boulders with the same momentum as the spacecraft? NASA’s groundbreaking experiment, the ...

NASA's DART mission successfully altered Dimorphos' orbit, but the impact unleashed over 100 boulders, significantly boosting ...

Asteroid Dimorphos. NASA's DART mission successfully altered an asteroid's orbit, but unexpected findings show that ejected ...

When NASA’s DART spacecraft collided with a small asteroid moon in late 2022, the impact made history. It was the first ...

The ejecta field consists of an asymmetric cone of dust that exhibits streamers and filaments, as well as over a hundred ...

NASA's DART spacecraft attempted to deflect an asteroid about the size of the Great Pyramid of Giza. New work tracking the debris has found a few fairly large surprises.

A new study of a star undergoing the throes of a supernova death has revealed that bursts of X-radiation known as fast-X-ray ...

When NASA's DART spacecraft slammed into the asteroid moon Dimorphos in September 2022, it didn't just change the asteroid's ...
