Examples
In older literature, the CMB is also variously known as cosmic microwave background radiation (CMBR) or "relic radiation".
In cosmology, from looking the CMBR, we can have some ideas about the topology of the universe.
Sufficiently sensitive radio telescopes can detected the CMBR as a faint background glow, almost exactly the same in all directions, that is not associated with any star, galaxy, or other object.
The detailed analysis of CMBR data to produce maps, an angular power spectrum, and ultimately cosmological parameters is a complicated, computationally difficult problem.
The fine-scale structure is superimposed on the raw CMBR data but is too small to be seen at the scale of the raw data.
