Researchers propose using X-ray bursts generated by a nuclear explosion as a potential method for deflecting asteroids on a collision course with Earth.

According to a study published in Nature Physics, this technique involves vaporizing the asteroid’s surface, altering its trajectory enough to avoid impact.

Following NASA’s DART mission, which successfully redirected an asteroid through kinetic impact, this X-ray method could enhance planetary defense strategies.

Laboratory experiments demonstrated the viability of the concept by heating mock asteroids with X-rays, causing vapor to escape and propel them in the opposite direction.

The researchers suggest that this method could deflect asteroids up to 4 kilometers (2.5 miles) in size, particularly effective in scenarios with limited warning time, Newsweek has reported.

The approach entails detonating a nuclear device near the asteroid to produce the necessary X-ray burst, providing a significant but controlled push without risking fragmentation of the asteroid.
