Lyman alpha emitter

Okay kiddo, imagine that there are really tiny things called atoms that make everything around us. Some fancy scientists have found a special kind of atom that gives off a special light that they call "Lyman alpha".

This special light is like a glow that helps scientists study and learn about the universe. They call the atom that emits this light a "Lyman alpha emitter".

Scientists use special tools to look at this special light and see how it can help them learn about space and how things work. It's like having a special flashlight that helps them see things they couldn't see before!
