New 3D model shows ‘dog bone’ asteroid is lighter than previously thought The new findings suggest the Kleopatra asteroid may be little more than a “pile of rubble" that likely formed when material ...

Recent research indicates that nuclear explosions could be used to prevent catastrophic asteroid collisions with Earth. The idea, while not new, is being revisited with fresh scientific rigor ...

As part of that research, Burkey and colleagues developed a new model that simulates what a nuclear detonation’s high-energy, X-ray emissions will do to an asteroid.

Tunguska explosion in 1908 caused by asteroid grazing Earth A new theory explains the mysterious explosion in Siberia, scientists say, suggesting Earth barely escaped a far greater catastrophe.

NASA scientists are using one of the agency's most powerful supercomputers to build 3D models of potential asteroid impact scenarios.
