Explore the Universe with NASA’s Overlap Zoo Project
Galaxies are incredible collections of stars, gas, and dust, but rare occurrences—like two galaxies appearing to overlap—offer unique opportunities for astronomers. NASA’s Overlap Zoo project invites you to help identify these fascinating galaxy pairs, which are essential for studying the distribution and effects of cosmic dust.
Understanding the Overlap
When two galaxies align, the background galaxy acts as a “flashlight,” shining through the dust of the nearer galaxy. This creates dark silhouettes that give astronomers insight into how dust interacts with light, allowing them to refine distance measurements to distant objects.
Get Involved!
Astronomers are facing a growing challenge: the increasing number of galaxy observations makes it tough to classify all potential overlapping pairs. That’s where you come in! As a volunteer, you’ll analyze images flagged by the Galaxy Zoo project.
You’ll learn to:
- Identify overlapping galaxy pairs
- Classify key features of each galaxy
- Mark their outlines
Your contributions will help create a comprehensive catalog of galaxy pairs, enhancing our understanding of cosmic dust and improving the accuracy of astronomical measurements.
