Space

This term we have started the topic about space. I have only been back at school now for a week after being away on holidays for a month, so i haven't learnt as much as some other people have. But i have learnt a bit about constellations and I've found a bit interesting about how people have named stars and visualised them into shapes. I would like to know what is the use of constellations. 

What has the space topic interested you about?
