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

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 ...

Earth captures second moon for a few weeks Asteroid 2024 PT5 part of the Arjuna asteroid belt Asteroid 2024 PT5 will not be visible to the naked eye ...

Earth is set to play host to a visiting “mini-moon.” An asteroid is expected to swing by Earth next week, then spend about two months orbiting the planet as it gets temporarily caught by Earth ...

Our descendants will — at some time in the future — almost certainly need to deflect an asteroid. But it's possible that in some scenarios a nuclear blast would be necessary. Especially if we ...

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 ...

Humanity could use a nuclear bomb to deflect a massive, life-threatening asteroid hurtling towards Earth in the future, according to scientists who tested the theory in the laboratory by blasting ...

The extinction of the dinosaurs has been a hotly debated topic for decades, and whether it was an asteroid, a volcanic eruption or even poisonous plant species. But researchers have found hard ...

The results show that X-rays could play an even bigger role than the initial shock wave itself, though more data needs to be gathered to form a comprehensive asteroid defense plan. Some 66 million ...

"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 ...
