From images taken by NASA's Hubble Space Telescope, for the first time astronomers have spotted a planet orbiting a star outside our solar system.
The planet, Fomalhaut b, maintains an orbit around the star Fomalhaut and has three times the mass of Jupiter.
Hubble has recorded events in our solar system. On July 24, 1994, the Hubble grabbed headlines with spectacular pictures of the Comet Shoemaker-Levy breaking up and then crashing into Jupiter. There are actually eight different crash sites in this photo.
On July 4-5, 2005, Hubble recorded the impact of a projectile that was launched by the spacecraft Deep Impact on a comet.
