Astronomy Photographer of the Year 2014 shortlist

Check out these amazing images of the stars and planets in our Solar System, which have made the shortlist for Astronomy Photographer of the Year.
These pics have all made the shortlist for Astronomy Photographer of the Year 2014. This image was taken while exploring a 1,300m lava cave in Iceland. The aurora at its peak gleams through the roof of the cave and despite only taking up a small portion of the photo, it steals the show.
