summary

Aided by a trick of gravity, astronomers have found a normal galaxy. Big deal, right? The thing is, where they found it is not normal: The light we see from it left the galaxy 12.4 billion years ago, meaning we’re seeing it as it was when the Universe itself was only 1.4 billion years old! That’s what makes this so weird. A normal galaxy has no business being there when the cosmos was so young. But yet, there it sits.
