Cucconi test

The cucconi test is like a very special game for scientists who study space. They use big listening tools on Earth to listen to noises coming from faraway places in space, like stars and planets. The cucconi test is one way they can tell if the sounds they are hearing are really from space or if they are just noise from our own planet. It's like when you're trying to listen to your mom talking on the phone, but someone else is talking too and it's hard to hear her. The cucconi test helps the scientists make sure they are listening to the right thing in space.
