Cosmos Redshift 7

Cosmos Redshift 7, or CR7 for short, is a special place in space. It's not just one star, but a whole galaxy! Think of a galaxy like a giant city of stars, gas, and dust all floating together.

CR7 is super, super old. It was around when the universe was only about 800 million years old. That's like the universe's toddler years!

It's so far away that the light we see from it today started its journey when dinosaurs might have still been stomping around on Earth.

CR7 is extra special because it's one of the first galaxies where stars began to form after the Big Bang. These first stars were HUGE and super bright, much bigger than our Sun. They were so hot they glowed with a special kind of light, like a bright blue-white color.

Scientists think these early stars might have been the very first ones to make the elements that make up everything around us, like the stuff in your toys and even you!

Finding CR7 was like finding a hidden treasure! Scientists used a giant telescope called the Very Large Telescope to spot it. It's so far away that it looks tiny, but it's actually a very big galaxy.

Because it's so far, the light from CR7 has traveled for billions of years to reach our eyes. It's like getting a postcard from the very beginning of time, showing us what the universe looked like when it was just starting out.

CR7 is important because it helps us understand how the universe began. By studying this ancient galaxy, scientists can learn about the very first stars and how they helped make the universe a place where planets and life could eventually form. It's like looking at the baby pictures of the universe to see how it grew up to be the amazing place we live in today.

It’s a peek into the universe’s earliest days!
