Dust clouds, star trails and meteor races: Astronomy Photographer of the Year award shortlist
The Royal Observatory has revealed its shortlist of candidates for the 2014 Astronomy Photographer of the Year award.
The selected photographs are not limited to celestial sights on our planet: they also include images from across our Solar System, galaxy and even further afield.
From a rare daytime scene of Jupiter moments before its astronomical alignment behind the body of the Moon, to the searing heat of the Crescent Nebula glowing in a whirl of red and blue, the collection represents what the judges consider to be the most incredible astronomical sights to have been captured over the last year.
The competition, run in association with BBC Sky at Night Magazine, welcomed entries from photographers of any professional level around the world via a dedicated Flickr group.
The winners of the competition's four main categories: Earth and Space, Our Solar System, Deep Space and Young Astronomy Photographer of the Year, will be announced on 17 September and then exhibited at the Royal Observatory in Greenwich until February 2015.
