Through their measurements of something called "cosmic microwave background radiation."

He found part of the cosmic microwave background radiation in 1964.

This is far less than the 2.7 K temperature of the cosmic microwave background radiation.

It started operations in 1999 to study the cosmic microwave background radiation and ran until 2008.

It was designed to measure the cosmic microwave background radiation.

For more information, see Discovery of cosmic microwave background radiation.

This leaves the problem of how to explain the microwave background radiation.

Their cumulative effect would give rise to the microwave background radiation.

The influx of energy would help explain the microwave background radiation.

Called the cosmic microwave background radiation, it was discovered accidentally in 1965.
