New research suggests Fomalhaut B may not be a planet after all
When the Hubble Space Telescope photographed the apparent exoplanet Fomalhaut b in 2008, it was regarded as the first visible light image obtained of a planet orbiting another star. The breakthrough was announced by a research team led by Paul Kalas of the University of California, Berkeley. The planet was estimated to be approximately the size of Saturn, but no more than three times Jupiters mass, or perhaps smaller than Saturn according to some other studies, and might even have rings.
