Some stars are surrounded by disks - vast spinning clouds of gas, dust, and chunks of rock where planets form and evolve. NASA's Wide-field Infrared Survey Explorer (WISE) mission collected images of more than two billion objects. Now scientists need your help finding which of these objects are stars with disks.
This long-running project discovered the Peter Pan disk phenomenon. Peter Pan disks are a kind of disk that retains gas far longer than most. More than 14 volunteers have become named coauthors of published papers through this project.
