This is an image of star HR 4796 in the constellation Centaurus. Two infrared wavelengths have been represented as light blue and red to make this picture. The disk of dust which is believed to have formed planets is seen in red here.

Astronomers have recently found what appears to be the clearest evidence yet of another solar system. Astronomers used the Keck II telescope in Hawaii to take images of a star called HR 4796 in the constellation Centaurus. The images show what appears to be a disk of dust around the star. This disk has an empty region in the middle that appears to have been swept clean of material. Scientists think that in this empty area planets could be forming (when planetary bodies form, an area often appears empty because excess material tends to coalesce onto already forming planetary bodies).The HR 4796 star is 220 light years away from Earth, so there will be no visiting this probable solar system any time soon. However, scientists will continue researching this star because what has been found there is of such significance in adding to our understanding of the formation of our own solar system.
"This may be what our solar system looked like at the end of its main planetary formation phase," said Dr. Michael Werner of JPL, who co-discovered the region, along with Doctors David Koerner and Michael Ressler, also of JPL, and Dana Backman of Franklin and Marshall College. "Comets may be forming right now in the disk's outer portion from remaining debris
