The cosmic microwave background CMB is a primordial glow of electromagnetic radiation which comes to us with almost equal intensity from every direction in the sky. The CMD shows a characteristic pattern of very finite bright and dim patches with a typical patch separation of 1° we would like to patch a telescope that can resolve these bright and dim patches distinguish two sources in the sky separated by 1°

suppose that we build our telescope to measure the CMB at frequency of 120 GHz is what diameter almost to the telescope circular aperture I have an order to just barely solve these features

16. The cosmic microwave background radiation (CMB) is radiation that bathes the Universe from every direction, and appears to be emitted by a blackbody at a temperature of 2.7 Kelvins. This radiation a. comes from stars. b. comes from supernovae. c. is the redshifted glow of the hot young universe, appearing much cooler today. d. consists of cosmic rays emitted by dying stars.

We often say that the cosmic microwave background radiation (CMB, or CBR) is a direct viewing of the Big Bang. But actually, the temperature of this black-body radiation (3 degrees K) is insanely low for the Big Bang. Why is it so low, when the Universe started out so hot? And why do we say now that the CMB represents light from about 400,000 years after the Big Bang, rather than the Big Bang itself?

What will the temperature of the cosmic microwave background be when the average distances between galaxies are 1.7 times as large as they are today? (Hint: The peak wavelength of photons in the background will then also be 1.7 times as large as it is today.)
