The cosmic microwave background (CMB) is the oldest light in the universe, a relic left over from the Big Bang itself. With a radio telescope, you can see its glow touch everything in space — and without one, you can see the mark it leaves in the static on an old TV set. But there's a peculiar dim in the CMB that has astronomers scratching their heads. Dubbed the Cold Spot, it was once thought to be caused by a "supervoid" where there was a dearth of galaxies. But new research says that can't be possible — and points to something much more fascinating.
