The cosmic microwave background ( CMB or CMBR) is microwave radiation that fills all space in the observable universe. It is sometimes called relic radiation. With a standard optical telescope, the background space between stars and galaxies is almost completely dark. However, a sufficiently sensitive radio telescope detects a faint background ...
e. 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. [ 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. There have been a variety of experiments to measure the CMB anisotropies and polarization since its first observation in 1964 by Penzias and Wilson.
Continuous marine broadcast. A continuous marine broadcast, or CMB, is a marine weather broadcasting service [1] operated by the Canadian Coast Guard. CMBs are programmed from the various Marine Communications and Traffic Services centres on the Atlantic, Pacific and Arctic coasts of Canada, as well as on the coasts of the Great Lakes.
China Merchants Bank. Deposit, loan, credit card and other banking services. China Merchants Bank ( CMB) ( Chinese: 招商银行; pinyin: Zhāoshāng Yínháng) is a Chinese bank headquartered in Futian District, Shenzhen, Guangdong, China. Founded in 1987, it is the first share-holding commercial bank wholly owned by corporate legal entities ...
China Medical Board was founded in 1914 as the second major project of the Rockefeller Foundation. With additional endowments from the Rockefeller Foundation, China Medical Board became an independent private foundation in 1928. CMB established Peking Union Medical College, which brought modern Western medical education to China and "quickly ...
Planck was a space observatory operated by the European Space Agency (ESA) from 2009 to 2013. It was an ambitious project that aimed to map the anisotropies of the cosmic microwave background (CMB) at microwave and infrared frequencies, with high sensitivity and angular resolution. The mission was highly successful and substantially improved ...
The Wilkinson Microwave Anisotropy Probe ( WMAP ), originally known as the Microwave Anisotropy Probe ( MAP and Explorer 80 ), was a NASA spacecraft operating from 2001 to 2010 which measured temperature differences across the sky in the cosmic microwave background (CMB) – the radiant heat remaining from the Big Bang.
