These photons fly uniformly through space from all directions, with an average temperature of 2.7 kelvins (° 455 degrees Fahrenheit), composing a cloud of radiation called the cosmic microwave background (CMB).

In 1992, NASA's Cosmic Background Explorer (COBE) first detected tiny temperature fluctuations, or anisotropy, in the CMB.

Inflation theory, first proposed in the early 1980s, predicts that a pattern of tiny temperature differences should exist in the cosmic microwave background (CMB), the afterglow of the big bang.

Other bubble universes might be detected in the subtle temperature variations of the cosmic microwave background radiation left over from the big bang of our own universe.

Experiments conducted in 1992 using NASA's Cosmic Background Explorer provided the first images of the temperature variations, and later observations from other instruments hinted at the presence of a peak.

These variations caused minute differences in the temperature of the early universe, which we can see in the cosmic microwave background.

PRIMORDIAL SWIRL The patterns and colors in this visualization represent the polarization and temperature of the cosmic microwave background in a small patch of space, emitted when the universe was about 380,000 years old.

The universe's age can be gleaned from the sizes of temperature ripples in the cosmic microwave background, such as these from the DASI telescope.

He matched this gap with an enormous «cold spot» — colder than the frigid temperatures of deep space — in the cosmic microwave background, the leftover radiation from the Big Bang.

The first results from the FIRAS experiment, using only 9 minutes of data, showed that the cosmic background radiation has exactly the black - body spectrum expected in the hot big bang theory, with a temperature of 2.735 + / - 0.060 kelvin.

Working with a tough mentor named Yakov Zel «dovich, Sunyaev showed that the tiny acoustic vibrations in the universe moments after the Big Bang could be observed as temperature and density variations in the cosmic microwave background (CMB) radiation, the faint afterglow of the Big Bang that suffuses the universe.

In addition to measuring the temperature of the cosmic microwave background, Planck can determine its polarization, the direction in which the waves of light vibrate as they move through space.

Would that be a Planck distribution representing microwave temperatures (3 K for example is the cosmic background microwave).

I had the impression that Mike was claiming that he couldn't get the Earth to cool to 3K and I was simply trying to point out that if you include radioactive decay, you wouldn't expect it to be 3K today in the absence of the Sun, and even if you ignore radioactive decay, it would still take longer than the age of the Universe for an Earth - like planet to cool to the temperature of the cosmic - background.

The best answer would be the temperature of the cosmic microwave background (2.75 K).
