Origin stories are a focus of many astronomical studies. Planetary formation, solar system formation, and even galaxy formation have long been studied in order to understand how the universe came to be where it is today. Now, a team of scientists from the Lyman Alpha Galaxies in the Epoch of Reionization (LAGER) consortium have found an extremely early “protogalaxy” that was formed approximately 750 million years after the big bang. Studying it can provide insights into that early type of galaxy formation and everything that comes after.
