What did Arno Penzias?

Arno Penzias, in full Arno Allan Penzias, (born April 26, 1933, Munich, Germany), German American astrophysicist who shared one-half of the 1978 Nobel Prize for Physics with Robert Woodrow Wilson for their discovery of a faint electromagnetic radiation throughout the universe.

What did Arno Penzias discover?

On May 20, 1964, American radio astronomers Robert Wilson and Arno Penzias discovered the cosmic microwave background radiation (CMB), the ancient light that began saturating the universe 380,000 years after its creation. And they did so pretty much by accident.

What did Penzias and Wilson receive for their discovery?

The Nobel Prize in Physics 1978 was divided, one half awarded to Pyotr Leonidovich Kapitsa “for his basic inventions and discoveries in the area of low-temperature physics”, the other half jointly to Arno Allan Penzias and Robert Woodrow Wilson “for their discovery of cosmic microwave background radiation.”

What were Arno Penzias and Robert Wilson doing at the time of their discovery?

Over two decades later, working at Bell Labs in Holmdel, New Jersey, in 1964, Arno Penzias and Robert Wilson were experimenting with a supersensitive, 6 meter (20 ft) horn antenna originally built to detect radio waves bounced off Echo balloon satellites.

How did Arno Penzias and Robert Woodrow Wilson discovered the cosmic microwave background?

But the CMB was first found by accident. In 1965, two researchers with Bell Telephone Laboratories (Arno Penzias and Robert Wilson) were creating a radio receiver and were puzzled by the noise it was picking up. They soon realized the noise came uniformly from all over the sky.
