A new debris disk is discovered by the Herschel Space Telescope around the red dwarf tertiary star in the famous Fomalhaut system.
The first science results from ALMA include remarkable images of the dust ring encircling the notorious Fomalhaut. Modeling of the ring’s morphology suggests the existence of two planets, each with a mass comparable to the mass of the Earth.
