An Exeter University lecturer is hoping to get more young people interested in science by posting a video about space on YouTube.
Dr Nathan Mayne's 15 minute presentation talks about the search for life on other planets and how looking at their atmosphere is key.
A senior lecturer in Astrophysics at Exeter University, he says that he wants to help educate people on space and get them excited about science.
