I am not entirely sure about the wavelength; however, the features of the background radiation agree very closely to what would be expected from the Big Bang theory.
The radiation was 100 times more than expected and they were certain it did not come from our galaxy. They reasoned that the Big Bang had released a tremendous blast of radiation and scattered the matter that condensed into galaxies.
I didn't check the year... But the cosmic background radiation is said to support the big bang theory, because it agrees with the radiation that is expected from an expanding Universe.
In our Universe, EM radiation can only come in discrete chunks called "photons." The energy of each individual photon depends on the frequency of the EM radiation. Frequency depends on wavelength (or vice-versa): the shorter the wavelength, the higher the frequency. Thus, short wavelength photons have more energy. That's just how our Universe operates, whether or not we like it.
Cosmic Microwave Background (CMB) Radiation.
The source of cosmic background radiation filled the entire universe.

either starlight spectra or moving galaxies.

cosmic microwave background radiation.
Big Bang Cosmology predicted the existence, isotropy, and spectrum of the CBR; all other hypotheses have no explanation for it. When one idea perfectly explains an undeniable fact of our Universe, and another utterly fails to do so; scientists tend to prefer the former idea.

I sent a form of thermal energy throughout the universe.
Where? Everywhere. This is the residual radiation, from when the Universe was very, very hot.
The cosmic background radiation is an observation of the effects of the Big bang [See related question] it does not effect the Universe changing in anyway.
The cosmic background radiation is believed to be the remains of the radiation emitted by the Universe when it started to get transparent - when it had cooled down to a temperature of about 3000 kelvin.
