Mysterious ripples found racing through planet-forming disk

Astronomers using NASA’s Hubble Space Telescope and the European Southern Observatory’s (ESO) Very Large Telescope in Chile have discovered never-before-seen moving features within the dusty disk surrounding the young nearby star AU Microscopii (AU Mic). The fast moving, wave-like structures are unlike anything ever observed in a circumstellar disk, said researchers of a new analysis. This new unexplained phenomenon may provide valuable clues about how planets form inside these star-surrounding disks.
