Deep space is the universe beyond our Earth. Many amazing planets, stars, and galaxies are made and can be found there.
Did You Know: Space – How many stars are there in the universe?
From Earth, we can see thousands of stars in the night sky, but there are many more farther out in space. In fact, there are more stars in the universe than grains of sand on all the beaches and deserts on Earth.
Counting stars
To figure out the number of stars in the universe, scientists multiply the number of stars in a galaxy by the number of galaxies they think there are.

This picture was taken by the Hubble Space Telescope. It shows a place in space where stars are formed.
What is the closest star to our sun?
Proxima Centauri
The closest star to our sun is called Proxima Centauri. It is very far away from the sun and from Earth—so far that light from it takes more than four years to reach us on Earth.
