In this lesson, we’ll meet Karen Masters, an astronomer who is studying and classifying distant galaxies. We’ll also learn how we can help her do her work by using a website called Galaxy Zoo. You can look at data from a sample of millions of galaxies and help astronomers understand the answers to big questions about the universe.
