We only know a small fraction about our universe and galaxies beyond our solar system and there are still many intriguing questions that need to be answered. Do aliens exist? How was the universe formed? Are there multiple universes?

One million Earths can fit in the sun:

This shows how huge our sun is compared to our home, planet Earth. The sun is the centre piece of our solar system and makes up 99.8% of the mass of the entire solar system.

Space debris can wipe out entire civilisations:

There are some rocks in space that could create huge craters and damage our home planet. Scientists fired a 350kg bullet into a huge comet in 2005, raising concerns of space debris. Debris could strike Earth at any time or any day and our planet could be destroyed if we are not prepared.

The universe contains over 100 billion galaxies:

We are part of only one solar system in our galaxy. Our galaxy, called the Milky Way, is made up of billions of solar systems just like ours. Billions of galaxies make up our universe such as the Tadpole Galaxy, Whirlpool Galaxy, and Black Eye Galaxy. This shows how small we are compared to the whole universe.

Our galaxy is 13.6 billion years old:

This shows how old our galaxy is and how Earth has only been around for a small amount of time compared to our galaxy. Earth is 4.54 billion years old. That is a difference of around 9 billion years!
