Hubble Spots First Potential Asteroid Collision
The X marks the spot of a suspected head-on collision between two asteroids imaged by the Hubble Space Telescopeís new-and-improved Wide Field Camera.

If itís confirmed by further observations, it would be the first time that scientists have detected the interplanetary collision between objects in the asteroid belt, though they believe that such occurrences are common.

The complex structure of the debris is what makes astronomers think they may be seeing something new around the sun. The main nucleus of the object, P/2010 A2, is actually located outside its dust halo, something thatís never been seen in a comet-like object before.

ďThe filamentary appearance of P/2010 A2 is different from anything seen in Hubble images of normal comets, consistent with the action of a different process,Ē said David Jewitt, an astronomer at the University of California Los Angeles, in a press release.
