People often ponder what happens we die, but have you ever wondered what happens when galaxies die? Prior to a few recent findings by the Sloan Digital Sky Survey and the journal Nature, we knew two things: half the galaxies in the universe are dead, and galaxies "quench" (die) when they stop making new stars.
