Biography

About

Arno Allan Penzias was born April 26, 1933, and became a physicist and radio astronomer working with sensitive instruments meant to pick up faint signals from space. In 1978, he and Robert Woodrow Wilson shared the Nobel Prize in Physics for discovering cosmic microwave background radiation — the afterglow of the universe's birth, a faint hum filling every corner of the sky. What they'd stumbled on while troubleshooting interference became the strongest evidence for the Big Bang, rewriting cosmology. He died January 22, 2024.

Astronomy leads us to an unique event, a universe which was created out of nothing and delicately balanced to provide exactly the conditions required to support life.
