The cosmic microwave background radiation is an emission of uniform black body thermal energy coming from all directions. Intensity of the CMB is expressed in kelvin (K), the SI unit of temperature. The CMB has a thermal black body spectrum at a temperature of 2.725 48 ± 0.000 57 K. [4]
The discovery of cosmic microwave background radiation constitutes a major development in modern physical cosmology. In 1964, US physicist Arno Allan Penzias and radio-astronomer Robert Woodrow Wilson discovered the cosmic microwave background (CMB) , estimating its temperature as 3.5 K, as they experimented with the Holmdel Horn Antenna .
A comparison of the sensitivity and resolution of WMAP with COBE and Penzias and Wilson's telescope, simulated data [1]. This list is a compilation of experiments measuring the cosmic microwave background (CMB) radiation anisotropies and polarization since the first detection of the CMB by Penzias and Wilson in 1964.
The discovery (by chance in 1965) of the cosmic background radiation suggests that the early universe was dominated by a radiation field, a field of extremely high temperature and pressure. [ 1 ] The Sunyaev–Zel'dovich effect shows the phenomena of radiant cosmic background radiation interacting with " electron " clouds distorting the ...
The new cosmic ray was detected by the Telescope Array experiment, which brings together 507 different stations in a grid of in the Utah desert to detect cosmic rays and other phenomena.
In 1964 the cosmic microwave background radiation was discovered as predicted by the Big Bang theory. The steady-state model attempted to explain the microwave background radiation as the result of light from ancient stars that has been scattered by galactic dust.
A second body has been found near where two sisters went missing in Scotland in early January after going on a night walk.. The discovery came on Friday, Jan. 31, after police announced they'd ...
A strand of human DNA is about 2.5 nanometers thick. (One micrometer is 1,000 times larger than a nanometer.) (One micrometer is 1,000 times larger than a nanometer.)
