Lindley Johnson has been a pioneer in blueprinting warning and response scenarios to any potential impact of Earth by an ...

A nuclear explosion might eventually be Earth’s only way to protect itself from a dangerous asteroid. But preparing for that ...

NASA is actively working on planetary defence against asteroids that could threaten Earth. Their new documentary highlights efforts being made.

NASA has just premiered Planetary Defenders, offering a fascinating look at the high-stakes work geared toward protecting Earth from any large asteroids discovered coming our way.

Planetary defenders tend to prefer deflection because it’s gentler and more predictable. Destroying the asteroid (experts use the term “disrupting”) involves breaking it into pieces ...

The space rock is expected to zoom past our planet today at a speed of around 45,991 miles per hour, according to NASA.

A so-called “city-killer” asteroid once feared to be on a collision course with Earth could instead crash into the Moon, according to updated observations by NASA scientists. Asteroid 2024 YR4, ...

A huge asteroid that was briefly feared to strike Earth now has a nearly 4% chance of smashing into the Moon, according to ...

But new direct observations of the asteroid by Nasa’s James Webb Space ... big hitting the Earth may warrant the development of deflection missions. “At this writing, a 2032 impact with ...

This is a still from an animation showing asteroid 2024 YR4 as it passes by Earth and heads toward its potential impact with the Moon. This 3D shape of the asteroid was determined from data ...

through its Double Asteroid Reflection Test (DART) mission. Dimorphos wasn't headed for a dangerous collision with Earth, but it was an ideal target to test a deflection plan that involved crashing a ...

serving as the first real-world test of asteroid deflection via kinetic impact. The spacecraft intentionally crashed into the moonlet of the asteroid Didymos and successfully altered its orbit by ...
