Galaxies are collections of millions, or billions of stars. The Milky Way is the galaxy in which we live, orbiting around it’s centre in a distant spiral arm.

Have you ever wondered how big a galaxy is? They contain millions to billions of stars but what does that really mean for size?

Reading about sizes in a book is one thing, but what if you could make an observation of a galaxy and then measure its size?

Have you ever wondered how big each of the planets is? Bigger or smaller than the Earth?

Supernovae are exploding stars which increase in brightness very suddenly and unexpectedly.

Asteroids are small, rocky objects that orbit the Sun. Most are located between the orbits of Mars and Jupiter. This area of our Solar System is known as the Asteroid Belt.

Is gravity the same everywhere? Experiment with how the ball reacts in each of the Solar System locations by dropping or throwing the ball. How similar or different is each location to Earth?
