Today, telescopes like Planck can observe this fossil light across the entire sky as the Cosmic Microwave Background
, or CMB.
In space, the radiation of the cosmic microwave background
, influenced by the squeezing of gravitational waves, was scattered by electrons, and became polarized, too.
The Cosmic Microwave Background
Radiation was discovered by accident in 1965 by two Bell Laboratory scientists, Arno Penzias and Robert Wilson, as they tracked down sources of radio interference.
Planck will study the Cosmic Microwave Background
- faintly glowing radiation left behind by the Big Bang which gave birth to the universe 13 billion years ago.

Author of over 500 papers and numerous books, Professor Rees is particularly known for advancing our understanding of the origin of the cosmic microwave background
radiation, as well as galaxy clustering and formation.
The region had already been identified as a "cold spot" because it stood out on a map of the Cosmic Microwave Background
(CMB), a faint echo of remnant radiation from the Big Bang that gave birth to the universe.
The mid-1960S detection of the cosmic microwave background
, a pervasive radiation field predicted by Big Bang theorists, turned professional opinion in cosmology sharply away from the steady state.
Theorists in the 1960s suggested that the primordial seeds of galaxies should be seen as ripples in the Cosmic Microwave Background
radiation emitted in the heat left over from the Big Bang, when the universe was a mere 350,000 years old.
This afterglow is called cosmic microwave background
The image shows the ``afterglow'' of the Big Bang, called the cosmic microwave background
, and ``freezes'' the universe at a point when it was only 380,000 years old.
The glow, called cosmic microwave background
radiation, carried an imprint of large waves to the detectors on Earth.
