ELI5: Explain Like I'm 5

Galaxy Zoo

Galaxy Zoo is like a big game where people look at pictures of the sky and try to find different shapes of galaxies, kind of like looking for different shapes in clouds in the sky. But instead of finding shapes like animals or cars, they look for long and skinny ones, round ones, and all kinds of other shapes too.

These galaxies are like big groups of stars that float around in space, kind of like our own Milky Way galaxy. But there are so many of them in the sky that it’s hard for one person to find them all. That’s why lots of people play Galaxy Zoo – they each look at different pictures and try to find different shapes so together they can find all the galaxies out there.

The fun part is that by finding all these different types of galaxies, they can help scientists learn more about space and how it works. It’s like being a space detective and helping solve mysteries about our universe!
