Fomalhaut

This white star is surrounded by a dust disk, which is in the process of forming planets similar to our solar system. Unfortunately the star has only a lifespan of about 1 billion years. Complex life probably can't form in this time.

The dust disk already contains a planet with about three times the mass of Jupiter, which orbits the star every 872 years in a distance of 114 AU. This was fotographed by the Hubble Space Telescope as first exoplanet in visible light. The photo was published on November 13th 2008, here you can see a detail of it.
