Every time scientists do or see something for the first time, it's special. We're discovering something entirely new about the universe we live in. Even when it comes to things we only see from far, far away can tell us more about life.
The weird thing about the latest discovery in the cosmos is that we're not 100% sure what happened even months later and with a staggering amount of data. This is a situation where scientists have observed something for the first time — but they can't quite agree on exactly what they've seen. It's still a mystery, but the theories are fascinating.
