Did you know we are part of a spiral galaxy called the Milky Way? Earth is located in an arm of the spiral.

When we talk about the universe we mean everything that exists. Galaxies, planets and everything in between. Scientists think the edge of the universe is expanding faster than the speed of light!

HOW BIG IS THE UNIVERSE?
It’s hard to imagine just how big the universe is. Scientists estimate that there are around 100 billion galaxies!! If you think the Milky Way ( our galaxy ) is thought to have between 200 and 300 billion stars like our sun, it’s pretty impossible to comprehend.

Much of the universe is actually empty space (dark matter and dark energy ) and the things we can see ( ordinary matter ) make up only 4-5% of the universe.

WHAT IS DARK MATTER?
Scientists think stars and planets would not move as they do in empty space, but so far we don’t have the ability to see or measure dark matter. Dark matter is thought to make up between 25-28% of the universe.

WHAT IS DARK ENERGY?
Dark energy is how scientists refer to the force that is thought to be behind the expansion of the universe. Dark energy is thought to make up between 67-70% of the universe.
