Cosmic microwave background-the energy left over from the Big Bang-provides a baby picture of the universe. Astrophysicist and curator Mordecai-Mark Mac Low explains this phenomenon and tells the story of its discovery.

Fantastic, thank you for keeping the explanation simple and therefore easy to understand.

I’ve watched a lot of videos about CMB but this the only video that made me understand! Thank youuu

The entire universe was once hotter than the surface of the Sun. What became of the light emitted by that hot universe? In this video, Mac Low explains how the cosmic microwave background-energy left over from the Big Bang-was discovered.

interesting

Nice video. One thing remains vague for me. If the initial cosmic radiation stretched from short wave lengths to long wave lengths over a period so that we could see it as CMB. This should not take more than 13.7 b years. In contrast we were able to see light from objects 13.7 b light years away. It was not mentioned that this light from these objects is stretched as CMB is. In fact any light from that far observed by any instrument should be a stretched in wave length from the starting point. Or there is no standard like light will get stretched from low wave length to high wave length after travelling 13.7 b light years. This is not clear. Red Shift gives about movement.

The CMB is the oldest light we can see; however we see light from objects *almost* as old, and it is indeed heavily stretched, though not as much as the CMB.

Fifty years ago today, two astronomers made a discovery that forever changed our understanding of the universe. On May 20, 1964, American radio astronomers Robert Wilson and Arno Penzias pointed their antenna at empty patches of sky, and stumbled on a low-level hiss that would turn out to be cosmic radiation-cosmic microwave background-evidence for the Big Bang theory of the beginning of the universe.
