Disk Detective

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.

What you'll do

View images of stars taken by multiple telescopes.
Examine the images for background sources of light or other interference that might mimic light from a disk.
Connect with scientists and other citizen scientists to research good disk candidates in greater depth.

Requirements

Time to get started: ~15 Minutes to complete online training.
Equipment: Internet connected mobile device or computer
Knowledge: None. In-project tutorial provided.

Get started!

Visit the project website.
Learn: Click “Get Started” and complete the tutorial to learn how to recognize debris disks.
Look for disks: Start looking for debris disks by comparing multiple images of the same star taken with different telescopes.

👁 A cartoon white magnifying glass is centered on a yellow sphere with a ring around it against a black background. The magnified image in the center of the square logo is meant to be a star encircled by a debris disk.

👁 we see a grid of four views of the same part of space, each taken by a different telescope. The images have black backgrounds with white and blue blobs. From upper left and moving clockwise, the images were made by: unWISE w3 (the brightest image), unWISE w1 (only three distinct white spots and two blue), Pan-STARRS g (all the spots are still visible, but each is smaller), and 2MASS J (same spots of light, smaller yet). Each image has a bright spot in the center surrounded by two red circles

You'll compare images of the same star at different wavelengths to help figure out if that star has a disk.

👁 Concentric rings surround a bright yellow circle in the center. The rings are yellow-orange in the middle, orange-red in the middle, and red and ragged on the outer ring. Text in the lower right corner of the image reads “Image of the HL Tau Disk from the ALMA Telescope” where ALMA stands for “Atacama Large Millimeter Array.”

Planets form from the vast clouds of gas, dust, and chunks of rock that surround some stars.
