The Hubble Space Telescope has spotted the gory aftermath of the first-ever intentional collision between a spacecraft and an asteroid, revealing a debris field of at least 37 "boulders" flung thousands of miles into space.

On Sept. 26, NASA's Double Asteroid Redirection Test (DART) spacecraft disintegrated as it smashed into the asteroid Dimorphos, which is 7 million miles (11 million kilometers) from Earth, successfully changing the asteroid's trajectory.
