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.

In the UK, we experience 4 seasons each year. These are spring, summer, autumn, and winter. You may have noticed that the weather changes during each season. But have you noticed any other differences? 

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

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.
