Astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) to discover the tale-telling signs of planets in the young, likely planet-forming disk around the star MWC 758. They obtained an “ultra” high-resolution image revealing the disk having not only an off-centered cavity but also a spiral arm corresponding to one previously seen in reflected light.

“What drives the various kinds of structures we see in planet-forming young disks around protostars? This is a question that has baffled astronomers for over a decade!”, pointed out by the lead author of this investigation, Ruobing Dong, at University of Arizona, USA, and Academia Sinica Institute of Astronomy and Astrophysics (ASIAA), Taiwan; “Our observations reveal a great amount of exciting new details in this system and provide crucial clues on their origins.”
