The Hubble telescope has been tracking a UFO in the solar system's asteroid belt since early January. The object - dubbed P/2010 A2 after it was discovered by the Lincoln Near-Earth Asteroid Research program sky survey - has traits similar to a comet, but the x-shape appears disconnected from the tail. NASA says that the strange object may be the product of the collision between two asteroids.
The object is the latest addition to the list of strange sightings in the sky over the past couple of months.
