Group of answer choices CBR correponds to a solar temperature of about 6,000 degrees and implies that the Universe was about 3K right after the Big Bang. The original CBR corresponded to a much higher temperature, but the expansion of the Universe has caused to be strongly Doppler-shifted toward longer wavelengths. Satellite-based telescopes were crucial to the discovery of CBR because much of the CBR spectrum cannot be detected through our atmosphere. The motion of the Earth produces a Doppler shift, which causes CBR to appear a little hotter in front of us and a little colder behind us. Data for CBR is collected by pointing telescopes to regions that do not appear to have any bright objects.arrow_forward
