Dusty Disk Ringing Declining Double Star Could Make Planets | Video

Astronomers tasked the Very Large Telescope Interferometer at ESO’s Paranal Observatory to image the gas and dust disk surrounding the dying double star IRAS 08544-4431. The ring is made of material blown by the red giant member of the pair and is remarkable similar to rings around young stars, suggesting old ones may also form at least a second generation of planets.
