What if you could take a baby picture of the ENTIRE UNIVERSE?

The Day Scientists Found Proof of the Big Bang!

How a teeny-tiny satellite changed everything we know about the universe

A tiny satellite proved the Big Bang really happened, winning scientists the Nobel Prize!

Picture this: It's September 6, 2006, and scientists are SO excited they can barely sit still! A tiny satellite called COBE (which stands for Cosmic Background Explorer) just won its creators one of science's BIGGEST prizes — the Nobel Prize in Physics!

But wait, let's rewind. Way back in 1989, NASA launched this amazing little satellite into space. Its mission? To look for something invisible — the leftover glow from when the universe was born!

You see, scientists believed that about 13.8 billion years ago (that's older than anything you can imagine!), the entire universe started with an enormous explosion called the Big Bang. Everything — every star, planet, and even YOU — came from that moment!

But how do you prove something that happened so long ago? That's where COBE became a superhero! It found the "baby picture" of our universe — tiny temperature differences in space that are like fingerprints from the Big Bang. These little differences eventually became the galaxies we see today!

💡 COBE measured temperatures in space that were only about 2.7 degrees above absolute zero — that's colder than anything on Earth!
