This leftover glow, called the Cosmic Microwave Background (CMB), is the oldest electromagnetic radiation, and it fills the entirety of our universe.

Scientists have created a new map of the dark matter in the universe. Using radiation left over from the Big Bang, researchers mapped the gravitational effects of the mysterious substance.

Scientists have claimed that evidence for past universes may exist in the night sky – namely the remnants of black holes from another universe. As reported by New Scientist, the idea is based ...

Technically, this afterglow is known as Cosmic Microwave Background (CMB) radiation, and it's been traveling through space for more than 13 billion years, since soon after the Big Bang first went ...

The CMB tells us lots of important information about what the universe was like long ago. According to the Big Bang theory, the early universe was very hot and full of radiation.

Among the most effective optical elements that absorb the short wavelength radiation but let the CMB pass through is alumina. But one challenge of using alumina is that it also reflects almost 50% ...

Planck’s main purpose was to map tiny variations in the CMB’s temperature across the sky, but the mission also measured the radiation’s polarization.

But new evidence shows that 10 to 15 percent of this radiation has been scattered since then. This indicates a re-warming of the universe which nobody had expected.

The CMB tells us lots of important information about what the universe was like long ago. According to the Big Bang theory, the early universe was very hot and full of radiation.

The CMB light was always around in the universe but couldn’t travel far at all until the first atoms formed. In fact, we know that it was released 380,000 years after the Big Bang. This sounds like a ...
