You know how when you play outside on a really sunny day and the sun is really bright and it’s hard to see things far away? Well, telescopes on Earth have to look through a lot of air, which is like a really bright sun for telescopes. When telescopes are in space, like on the JWST, they don’t have to look through all that bright air and can see things much better.
