That's the conclusion of a four - year mission conducted by the European Space Agency's Planck spacecraft, which has created the highest - resolution map yet of
the entire cosmic microwave background (CMB)-- the first light to travel across a newly transparent universe about 380,000 years after the big bang.
So said Dragan Huterer of the University of Michigan, Ann Arbor, the night before the European Space Agency released the highest - resolution map yet of
the entire cosmic microwave background (CMB), relic light from the primordial universe.
Not exact matches
The puzzle emerged after astronomers measured the
cosmic microwave background — a bath of radiation, left over from the Big Bang — and found only slight variations in its temperature across the
entire sky.
The
cosmic microwave background is a faint glow that pervades the
entire sky, dating back to just 380,000 years after the big bang.
As it was created nearly 14 billion years ago, this light — which exists now as weak
microwave radiation and is thus named the
cosmic microwave background (CMB)-- permeates the
entire cosmos, filling it with detectable photons.
