Overlap Zoo

Confirm and describe overlapping galaxy pairs to reveal interstellar dust. For anyone with an internet-connected computer. The post Overlap Zoo appeared first on NASA Science .

Overlap Zoo

Galaxies, enormous assemblies of billions of stars, gas, and dust bound by gravity, occasionally align in perfect alignment from Earth's perspective. This cosmic convergence, known as overlapping galaxies, provides a unique opportunity for scientists to study dust that is otherwise invisible.

Citizen scientists participating in the Overlap Zoo project can assist in this research. By examining images of these galaxies, volunteers can aid in verifying their presence, classifying key features of each galaxy, and marking their outlines. This work contributes to the creation of the first comprehensive catalog of galaxy pairs, enhancing the accuracy of astronomical estimates related to cosmic dust.

The Overlap Zoo project is an online initiative launched in 2026. Participants will learn to identify two types of galaxies - smooth and featured - within these pairs. They will also examine images to determine the orientation of galaxies in space. The project requires only 10-15 minutes to complete a tutorial, after which volunteers can dedicate as much time as they wish to review images and record their observations.

No prior knowledge is necessary; an in-project tutorial provides all the required information. The project's Research page explains the significance of overlapping galaxies in astronomy, particularly for those studying cosmic dust. The Frequently Asked Questions (FAQs) page offers additional practical guidance for project members.
