For thousands of years humans have wondered how and when the universe first began. Now, thanks to some photographs taken by Wilkinson Microwave Anisotropy Probe (WMAP), scientists are much closer to understanding, even seeing, the universe in its beginning years.
This is all possible thanks to the WMAP satellite in orbit about one million miles above Earth. The satellite is specially designed to record one kind of cosmic energy: microwave radiation. It can use this radiation to show us what the universe looked like 13.3 billion years ago!
Wait a minute ... how can this satellite show us a picture of the universe billions of years ago? The Big Bang created the universe in a huge explosion, and at the same time it created a specific field of radiation—called the cosmic microwave background, or CMB. This CMB still lingers in the universe today. What the satellite actually does is take pictures of the CMB.
So what did scientists learn from these new pictures? First, they learned that stars formed very soon— merely 200 million years— after the Big Bang. And they were able to confirm estimates of the universe’s age: it was born about 13.7 billion years ago. This is the age that scientists long suspected to be true, but now they have the birthday pictures to prove it!
