Detailed explanation-1: -Its detectors were trialled in the Antarctic Viper telescope as ACBAR (Arcminute Cosmology Bolometer Array Receiver) experiment-which has produced the most precise measurements at small angular scales to date-and in the Archeops balloon telescope.
Detailed explanation-2: -Astronomers detect the Cosmic Microwave Background (CMB) as an extra noise equivalent to a black body radiating at a temperature of 2.73 K. They do this with an instrument called a microwave radiometer. A radiometer is a radio telescope whose response is calibrated with known temperature sources.
Detailed explanation-3: -COBE revolutionized our understanding of the early cosmos. It precisely measured and mapped the oldest light in the universe–the cosmic microwave background. The cosmic microwave background spectrum was measured with a precision of 0.005%. The results confirmed the Big Bang theory of the origin of the universe.
