Astronomers have discovered what may be a free-floating black hole by observing the brightening of a more distant star as its light was distorted by the object's strong gravitational field -- so-called gravitational microlensing.

What they found suggests that this asteroid is a piece of the same stuff that coalesced into our sun four-and-a-half billion years ago.
