A new assessment of the Cosmic Microwave Background shows that the oldest stars ignited 150 million years later than previously thought. It's a realization that's forcing cosmologists to rethink the 13.8 billion year history of the Universe.
Astronomers have long sought tangible proof that the Big Bang caused the universe to violently and exponentially expand in the first few milliseconds of its existence. Now they have it, thanks in part to a radio telescope in Antarctica that recently detected primordial gravitational waves, the "smoking gun" evidence…
This is a map of the entire universe, specifically of the cosmic microwave background radiation that formed as a remnant of the Big Bang. And the circled region is where the CMB is so cold that it defies easy explanation.
