Formalhaut is one of the brightest stars in the night sky and located in the constellation Piscis Austrinus. It is a young star with a debris disk. In 2008 astronomers reported the discovery of a planet orbiting the star within the debris disk. Images from the Hubble space telescope show motion consistent with a Keplerian orbit that crossed the disk. However, there are still debates about where the observed emission is coming from. The object may be an isolated dust cloud or even a background neutron star.

Fomalhaut
This false-color composite image, taken with the Hubble Space Telescope, reveals the orbital motion of the planet Fomalhaut b. The planet will appear to cross a vast belt of debris around the star roughly 20 years from now. If the planet's orbit lies in the same plane with the belt, icy and rocky debris in the belt could crash into the planet's atmosphere and produce various phenomena. The black circle at the center of the image blocks out the light from the bright star, allowing reflected light from the belt and planet to be photographed.
