Robert Wilson facts for kids
Robert Woodrow Wilson (born January 10, 1936) is an American astronomer who won the Nobel Prize. He is famous for helping to find the cosmic microwave background radiation (CMB) in 1964. This discovery was a big step in understanding how our universe began.

Who is Robert Wilson?
Robert Woodrow Wilson was born in Houston, Texas. He grew up with a strong interest in science and how things work. He went to Rice University and then got his PhD in physics from the California Institute of Technology (Caltech).
Early Career and Research
After finishing his studies, Wilson started working at Bell Labs in New Jersey. This was a famous research center where many important scientific discoveries were made. He worked with another scientist named Arno Allan Penzias.
The Big Discovery
In 1964, Wilson and Penzias were working with a large antenna at Bell Labs. They were trying to improve satellite communications. Their goal was to remove all sources of unwanted radio signals, or "noise," from their antenna.
A Mysterious Hiss
No matter what they did, they kept hearing a faint, steady hiss or buzz coming from every direction in space. They tried everything to get rid of it. They even cleaned pigeon droppings out of the antenna, thinking that was the cause! But the noise remained. It was a mystery.
What Was the Noise?
This mysterious noise turned out to be something incredibly important. It was the cosmic microwave background radiation (CMB). This radiation is like an echo or leftover heat from the very early universe. Scientists had predicted that such radiation should exist if the universe started with a "Big Bang."
Why is the CMB Important?
The discovery of the cosmic microwave background radiation provided strong evidence for the Big Bang theory. This theory says that the universe began from a very hot, dense state and has been expanding ever since. The CMB is the oldest light we can see, showing us what the universe was like when it was only about 380,000 years old.
Winning the Nobel Prize
Fourteen years after their amazing discovery, Robert Wilson and Arno Penzias were awarded the 1978 Nobel Prize in Physics. They shared the prize for their groundbreaking work on the cosmic microwave background radiation. Their finding helped shape our modern understanding of the universe.
