Please read the following. It specifically states that the Milky Way is the main source of cosmic noise.

If you want to learn more spend some time Googling. You'll find that the noise temperature of the Milky Way reaches as much as 1400 degrees Kelvin, or an equivalent noise figure of about 8 db. With most good preamps at 3 dB NF or less, an 8 db noise figure due to cosmic noise is not "hair-splitting".
