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.
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.
For most cosmologists, the refutation of the steady-state theory came with the discovery of the cosmic microwave background radiation in 1965, which was predicted by 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.
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.

Theories of the universe are cosmologies. There are three main theories concerning our universe. These are the big bang theory, the steady state theory, and the oscillating universe theory. Each of these attempts to account for the observed expansion of the universe. So far the big bang theory is far and away the strongest of these three. If there was a big bang, there should be microwave background radiation. This radiation has been observed, and the age of the universe calculated to 13.7 billion years.'What are the theories of the universe' in Spanish = 'Cuales son las teorias del universo?'
The 'big bang' theory.
Note that it also helped support the theory of inflation. The reason is that the observed radiation very closely matched what was expected from the theory.
There were several parts to this discovery; for instance, theoretical calculations (based on the General Theory of Relativity) that showed that (under most circumstances) the Universe could not remain static; the discovery that all distant galaxies move away from us (the farther away they are, the faster they move away); and the discovery of the cosmic microwave background radiation.
The age of the universe is determined by CMBR, which is left over energy from the Big Bang Theory. CMBR stands for Cosmic Microwave Background Radiation.

Edwin Hubble was one of the scientists who realized that the red-shifted light from far-away galaxies indicated that the universe is expanding.
The leading scientific theory regarding the start of the universe is a cosmological model called the "Big Bang", which asserts the universe started out compressed, very hot and dense, that visible matter in its current form was consequent to an outward explosion. Evidence to support the theory includes the currently observable expansion of the universe, and a residual background radiation apparent in all directions.
