The cosmic microwave background is a sea of photons (light particles) left over from the big bang that pervades all of space at a temperature of minus 270 degrees Celsiusâ##a mere 3 degrees above absolute zero.

Light from the cosmic microwave background is polarized mainly due to the scattering of photons off of electrons in the early universe through the same process by

On 21 march, the Planck space telescope team released the highest-precision map yet of the cosmic microwave background (CMB),

Homing in on the cosmic microwave background In 1965, Arno Penzias and Robert Wilson discovered the cosmic microwave background. Their giant but crude microwave receiver saw the radiation as being the same in all directions,

occurring at 2. 7 kelvin. NASA/WMAP SCIENCE TEAMIT was not until the launch of the Cosmic Background Explorer (COBE) spacecraft that astronomers could begin to see variations in the background, at levels of 1 part in 100,000.

provides a capstone to the study of the cosmic microwave background. But unambiguous confirmation of a cosmic burst of expansion known as inflation remains elusive.

#Planck telescope peers into primordial Universe The Planck space telescope has delivered the most detailed picture yet of the cosmic microwave background, the residual glow of the Big bang. Unveiling the results from the##700-million (US$904-million) European space agency (ESA) probe,

The cosmic microwave background radiation studied by Planck dates from about 380,000 years after the Big bang, by

Since the cosmic microwave background was detected first in 1964, two space-based experiments#the Cosmic Background Explorer (COBE) and the Wilkinson Microwave Anisotropy Probe (WMAP)# have mapped the tiny temperature variations within it.

The simplest models of inflation predict that fluctuations in the cosmic microwave background should look the same all over the sky.

ever since appear in every direction in the sky as the cosmic microwave background (CMB) radiation. But other things apart from gravitational waves such as dust can emit polarised photons.
