If you can't watch the video,

Universe Today describes the story nicely:
"Astronomers have known for some time that a star named SAO 206462 has a disk surrounding it, and have studied it with all available techniques including with Hubble chronographic imagery. But new high contrast observations with the Subaru Telescope has shown a surprising double-spiral feature in the disk, which may point to planets in the act of forming."
