The CMB was discovered by accident in 1964 by scientists Wilson and Penzias, who thought it was caused by pigeon droppings. All that aside, they won the 1978 Nobel Prize for physics. The CMB represents leftover radiation from the Big Bang, and was formed about 380,000 years after the universe began.
