Astronomers are baffled by this image of an X-shaped celestial object which was recently photographed by the Hubble Telescope. One theory is that it is the result of a collision between two asteroids, a scenario which, if accurate, would be the first time such an event was captured on film. However, alternative theories abound, including that it is a "message" from God, the "blue star" predicted by the Hopi Indians, or even an alien spaceship. More on the story here.
