Did you know the Earth is travelling around the Sun at nearly 107,000 kilometres per hour?

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!

The Sun is a constant presence in our life on Earth. It gives us the heat and light we need to survive. But it is not a stable place. The Sun is a ball of hot plasma which is constantly changing.

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

Star clusters are large groups of stars. These clusters provide fantastic (in fact, out of this world(!)) laboratories for us to study populations of stars.

An exoplanet is a planet which orbits a star that is not our Sun. The first exoplanet was discovered in 1992. It was found in orbit around the pulsar PSR 1257+12.

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

Many years ago, a mathematician named Johannes Kepler created a set of rules explaining planets' movement in our Solar System.
