How does cosmic background radiation provide evidence for the Big Bang theory?
The Cosmic Microwave Background Radiation (CMBR) is an isotropic (to one part in 10,000) and continuous radiation from outer space, whose spectrum is identical to that of a blackbody at 2.7K . All of these absolute facts are easy to explain if one assumes Big Bang Cosmology to be true. Indeed, they were predicted by proponents of BBC 18 years before anyone looked for radiation from space. Nothing about CMBR -- not even its existence -- can be explained by any alternative to BBC. Those who deny BBC are reduced to stating, "I agree to the facts about CMBR, but I have absolutely no explanation for its existence, isotropy, or spectrum."
What are the pros and cons of the microwave cosmic background radiation theory?
Not sure what you mean by "theory" and not sure what you mean by "pros and cons." The MCBR (actually the "CMBR") exists, and its spectrum is EXACTLY as predicted by the hypothesis of our Universe having begun to expand from great density about thirteen billion years ago. Proponents of every other hypothesis about our Universe have to state, "I don't know WHY the CMBR is there, and I don't know why it has the spectrum it has. It's just there and I can't explain it."
What has cosmic microwave background radiation?
The CMBR is microwave radiation coming to our Earth with the same intensity (to within one part in 100,000) from all parts of the sky. Its spectrum is exactly that of a black-body -- ie, like that of a glowing object -- at a temperature 2.7 degrees above absolute zero. It is believed to be the remnant of recombination, 377,000 years after the Big Bang. No other hypothesis about our Universe can explain the CMBR other than saying, "It's just there and I don't know why it should be."
What did the COBE satellite find that suggests that the big bang explosion occurred?
The CoBE (Cosmic Background Explorer) proved, beyond any doubt, that the spectrum of the CMBR is that of a black-body of temperature 2.7K -- some researchers were finding slight differences from this. The VERY minor anisotropies (about one part in 10,000) found in the CMBR are consistent with matter clumping in the early Universe, just enough to produce galaxies. Note that WMAP and the Planck Probe have done even more precise measurements, and continued to get results consistent with CoBE.
Who discovered Saturn moons?
The first person to discover Saturn`s moons was Christian Huygens in 1655. The following moons discovered in order are: Titan Discovered:1655 Discovered by:Christian Huygens Iapetus Discovered:1671 Discovered by:Giovanni Cassini Rhea Discovered:1672 Discovered by:Giovanni Cassini Tethys Discovered:1684 Discovered by:Giovanni Cassini Dione Discovered:1684 Discovered by:Giovanni Cassini Enceladus Discovered:1789 Discovered by:William Herschel Mimas Discovered:1789 Discovered by:William Herschel Hyperion Discovered:1848 Discovered by:William Lassell Phoebe Discovered:1898 Discovered by:William Pickering Janus Discovered:1965-1966 Discovered by: Audouin Dollfus Epimetheus Discovered:1966 Discovered by:Richard Walker Helene Discovered:1980 Discovered by: Pierre Laques Telesto Discovered:1980 Discovered by:Bradford Smith Calypso Discovered:1980 Discovered by:Dan Pascu Prometheus Discovered:1980 Discovered by:Stewart Collins Pandora Discovered:1980 Discovered by:Stewart Collins Atlas Discovered:1980 Discovered by:Richard Terrile Pan Discovered:1981 Discovered by:Showalter Other astronomers:Kevin Beurile, Brett Gladman, Matthew Holman and others.

What is cmbr?
Cell Membrane Binary Ribosome
How is the age of the Universe determined?
The age of the universe is determined by CMBR, which is left over energy from the Big Bang Theory. CMBR stands for Cosmic Microwave Background Radiation.
How is the wavelength of CMBR likely to change if at all over the next billion years?
The wavelength will increase as the universe continues to expand.
How does cosmic backround radiation differ from the big bang?
Cosmic microwave background radiation was predicted by Big Bang Cosmology about 16 years before the former was discovered -- by accident. The existence, isotropy, and spectrum of CMBR are all exactly as predicted by BBC, and all alternatives to BBC are reduced to stating, "It's just there and there is absolutely no explanation for it."
What do we call objects that emit light in space?
Stars, quasars, clusters, nebulae, galaxies, superclusters, the CMBR (Cosmic Microwave Background Radiation).
What energy source does the earth obtain most of its energy from?
The Sun. Second, the CMBR (C osmic M icrowave B ackground Radiation).
Can the CMBR be redshifted starlight?
The odds are very much against it. The CMB matches expectations following from the Big Bang too well for it to be coincidental.

A sentence for cosmic?
In the 1960s, microwave radiation was detected coming from space and no particular source, and this radiation was dubbed the Cosmic Microwave Background Radiation (CMBR).
