Cosmic Microwave Background
Cosmic Microwave Background (CMB) radiation is the 'afterglow' of the Big Bang, dating back to about 380,000 years after the universe began. It was discovered by accident in 1964 by two radio astronomers who initially thought the signal was interference caused by pigeon droppings on their antenna.
