Glacier (Halo 5: Guardians map)

The good news is that scientists believe they've figured out how much starlight the universe has ever produced since the Big Bang. Exciting. The bad news? Well, apparently star production peaked a long, long time ago, and ever since, the universe has been in the process of dying. Only seven new stars are born a year these days. You can keep buying green bananas, though; there's time: We still have many billions of years before the stars that already exist go dark and cold.
