We’ve known about the existence of galaxies for about a hundred years, but how well do we actually know the extragalactic universe? In today’s episode, we dive deep on the earliest galaxies in the universe. Sanika covers her first bite on paradoxical galaxies that seem to be the deadest where we expect them to be alivest, and Shashank shows us a source of hidden mass in ancient galaxies that for once isn’t dark matter.
