Nobel Prize for Cosmic Microwave Background Discovery

Arno Penzias and Robert Wilson received the Nobel Prize for discovering cosmic microwave background radiation, confirming the Big Bang theory.

In 1978, Arno Penzias and Robert Wilson of Bell Labs were awarded the Nobel Prize in Physics for their 1964 discovery of cosmic microwave background (CMB) radiation — a faint thermal glow permeating the universe in all directions. The CMB is the remnant radiation from the Big Bang, emitted roughly 380,000 years after the origin of the universe. Their accidental discovery, initially mistaken for antenna noise, provided powerful confirmation of the Big Bang theory and showed that the universe appears the same in all directions (isotropic) at the largest scales, fundamentally shaping modern cosmology.
