An April 2021 event demonstrated how often close encounters can occur when a tiny 4-meter asteroid flew within 19,800 ...

The European Space Agency (ESA) is set to launch a mission that will assess how effective humanity could be in protecting Earth from an asteroid impact. Called Hera, the mission will visit a rock ...

The huge asteroid that hit Earth and wiped out the dinosaurs 66 million years ago was not alone, scientists have confirmed. A second, smaller space rock smashed into the sea off the coast of West ...

It's well known that the reign of the dinosaurs came to an end when a giant asteroid smashed into Earth 66 million years ago. But a new study suggests that this huge asteroid wasn't alone.

But experts say the asteroid was an important milestone in planetary defense research. Though there are hundreds of moons in our solar system, our planet only has one. And while thousands of ...

"Understanding how different asteroid materials vaporize and deflect will be critical for preparing for a planetary defense mission, should the need arise." When asteroids hurtle towards Earth in ...

Beginning Sunday, Earth's skies will soon have a temporary visitor. On September 29, an asteroid dubbed 2024 PT5 will become a "mini-moon" of sorts, temporarily entering Earth's orbit for almost ...

Radiation from a nuclear explosion can vaporize the surface of an asteroid and change its trajectory, a new study finds. An X-ray pulse may be able to vaporize the surface of an asteroid and ...

According to experiments and computer simulations, the radiation of a nuclear blast could be enough to change the trajectory of an asteroid threatening Earth—if spotted in time. About 66 million ...
