Welcome to Rubin Comet Catchers! Update December 14, 2025: Thanks, everyone, for all your hard work! Colin is back from broken bones and is excitedly examining the classification data! Meanwhile, we are preparing to upload a few more recently discovered objects from Data Preview 1! Meanwhile, check out this YouTube video featuring Colin on a show he hosts about the upcoming Rubin Observatory! It features Citizen Science, and Clare Higgs of Rubin Education and Public Outreach presents, too! Thanks again, everyone! We cannot do this without you! We also have a sister Rubin project! Check out Rubin Difference Detectives.

Important Notes: We have LSSTCam images! And they feature the interstellar comet 3I/ATLAS!! This first set will appear as part of the training images, and you’ll get a note when you see it! All other Rubin images are from the NSF-DOE Vera C. Rubin Observatory's Data Preview 1 (DP1) dataset, using the special commissioning camera, which is just a small taste of what's to come! As a result, we expected everything to be classified pretty quickly, so the number of classifications per image is set high to give everyone a chance to participate. If you want fresh data (or we’re out), please visit our sister project Active Asteroids for a great opportunity to discover active asteroids and other comets in Dark Energy Camera data! Note too that here in Rubin Comet Catchers, we have known comet images from the Active Asteroids project as part of our training dataset!
