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

The temperature on Earth is just right for life to exist. If it was too hot or too cold it would not be habitable.

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 likely heard about the Universe expanding. Or that redshift can tell us about the movements of galaxies. Both are difficult ideas to imagine and understand.
