Measurement

Einstein showed that the speed of light is a universal constant. This means that it always travels at the same speed in a vacuum.

You may know that Jupiter is the largest planet in the Solar System, but do you know how much larger than the Earth it is?

Find out by creating a scale model of each planet in our Solar System!

Impact craters are made when a space rock (called a meteorite or asteroid) hits a rocky planet or moon. The impact makes a round hole in the surface, called a crater.

Use our simulator to investigate the effect of gravity on other worlds. Then use your measurements and a bit of maths to calculate the strength of gravity in each location across the Solar System!

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

Our Solar System contains the Sun, 8 planets, and many small objects like dwarf planets, moons, and

You have probably seen the Moon in the sky but have you ever studied it in detail?

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.
