It’s the oldest, most distant light we’ve ever seen, left over all the way from the Big Bang. But where, exactly, is it?

As they reported in a study in Physical Review Letters, researchers from the University of Manchester searched for hints by comparing the distribution of galaxies to the cosmic microwave ...

(via Sabine Hossenfelder) In the Big Bang Theory, the cosmic microwave background — microwave-range radiation that floats through the entire universe at a steady 2.7 Kelvin — is evidence that a hot ...

The earliest signal we’ve ever directly detected from the Universe comes to us from shortly after the Big Bang: when the Universe was merely 380,000 years old.

Two scientists, Arno Penzias and Robert Wilson, discovered the cosmic microwave background in the mid-1960s while testing a large radio antenna for Bell Laboratories. They detected a constant ...

A new analysis of ‘cool’ spots in the cosmic microwave background may cast new doubts on a key piece of evidence supporting the big bang theory of how the universe was formed. Two scientists ...

The photos show light, dark and the polarization of light—background radiation known as the cosmic microwave background, and details the movement of hydrogen and helium gas at the beginning of ...

"What is cosmic microwave background radiation? Did it happen after the Big Bang?" – Sreehari, aged nine, Kerala State, India ...

But in 1964, Bell Labs researchers Arno Penzias and Robert Wilson accidentally discovered the microwave remnants of the Big Bang, the cosmic background radiation, using the antenna, earning it a ...

No matter in what direction you look, no matter how far out you look, everything in the cosmic microwave background looks pretty much the same.
