In 1965, Radio astronomers Arno Penzias and Robert Wilson discovered Cosmic Microwave Background radiation at the temperature of -454.765 degree Fahrenheit, or 2.725 degree Kelvin. This provided evidence that the big bang caused extreme heat that is still mesurable.

NASA launches the Cosmic Background Explorer to search for radiation in the universe. The team announced that they successfully mapped primordial hot and cold spots in the cosmic background radiation. These are related to the gravitational fields from the early universe.

The discovery of Quasars supported the Big Bang theory and went against the Steady State theory. According to the Steady State Theory, these quasars should be found all throughout the galaxy, but they are only found on the outskirts which supports the Big Bang theory in which the universe is constantly expanding.
