Galaxy Zoo

Compare galaxies to understand their evolution.

What is Galaxy Zoo?

In their quest to find all the stars in the Universe, researchers have to go through a vast number of images. But with the help of millions of people, the task can go much faster! Galaxy Zoo compares the galaxies of the past with the galaxies of the present, giving us a clear understanding of what affects their growth – mergers, active black holes, or basic star formation.

What do you do?

In this project you classify the shapes of galaxies from images taken by telescopes. You have to observe a picture and run through a few selection options to fully classify the shape you see. To help you, there are examples at each step.
