Now in its 15th year, the annual competition includes nine categories such as Skyscapes, Aurorae, Our Sun, Our Moon, and Young Astronomy Photographer of the Year. The winners will be announced on 14th September 2023, with all winning and exceptional shortlisted images set to feature in an exhibition at the National Maritime Museum in London, opening on 16th September. The competition offers a grand prize of £10,000 to the overall winner. The winners of all other categories, including the Young Astronomy Photographer of the Year, will receive £1,500.
