NASA Calls on Citizen Scientists to Help Reveal Cosmic Dust Through Overlapping Galaxies
A new citizen science project invites volunteers to study rare instances where galaxies appear to overlap from Earth's point of view.

NASA has launched a citizen science initiative asking the public to help identify and study overlapping galaxies, rare alignments that can reveal hidden cosmic dust, according to the agency.
Galaxies are vast collections of billions of stars, gas and dust held together by gravity, scattered across the immensity of space. Occasionally, two galaxies line up from the perspective of Earth or a space telescope and appear to overlap in the sky.
Why overlaps matter
These rare overlapping alignments allow scientists to study dust in the foreground galaxy by observing how it absorbs or scatters light from the background galaxy, offering a method for measuring dust properties that would otherwise be difficult to detect directly.
The project, named Overlap Zoo, invites volunteers without specialized astronomy training to review images and help identify these overlapping systems, contributing to a broader catalog that researchers can then study in greater depth.
Crowdsourced identification efforts like this one allow NASA and partner researchers to process far more imaging data than professional astronomers could review alone, drawing on the collective effort of public volunteers.
Further details on how to participate are available through NASA's citizen science portal.
