Planets like ours form in disks around stars. Citizen scientists have used Disk Detective to find thousands of these disks, including new kinds of disks that had never been seen before, like the "Peter Pan Disk" illustrated here (credit: Jonathan Holden). We're working on a new version of Disk Detective that will be even more powerful. Send an email to firstname.lastname@example.org to join our email list and help us plan the relaunch!
