Astronomy Photographer of the Year showcases the world's best space photography, from spectacular skyscapes to mind-blowing images of distant planets and galaxies.
Every year, photographers from across the globe compete to be part of the final exhibition and take home the prestigious title. Photographers of all skill levels are invited to submit up to 10 images to the competition.
There are separate photography prizes open to adults, young photographers and astrophotography newcomers. A full list of competition categories is below.
All entrants have a chance of winning cash prizes, seeing their image displayed in an exhibition at the National Maritime Museum, a year’s subscription to BBC Sky at Night magazine, and a copy of the Astronomy Photographer of the Year publication.
