An enigmatic object once thought to be a massive exoplanet is more likely to be the remnants of a catastrophic collision between two comet-like bodies, two US astronomers have shown. Andras Gaspar and George Rieke at the University of Arizona made the discovery after re-analysing observations of the Fomalhaut system made by the Hubble Space Telescope (HST). Their proposal could improve our understanding of how orbiting bodies can destroy each other, even in more peaceful star systems.
