Explanation: 

Detailed explanation-1: -Whereas today’s Universe is immersed in cosmic background radiation with a temperature of 2.7 Kelvin (-270.45 °C), less than a billion years after the Big Bang its temperature was approximately 20 K (-253.1 °C).

Detailed explanation-2: -This is called the 3 Degree Kelvin Background Radiation, or the Cosmic Background Radiation, or the Microwave Background. These names come about because this radiation is essentially a black body with temperature slightly less than 3 degrees Kelvin (about 2.76 K), which peaks in the microwave portion of the spectrum.
