Royal Observatory Greenwich Announces the Winner of Astronomy Photographer of the Year 15
The overall winners of the Royal Observatory Greenwich’s Astronomy Photographer of the Year 15 are Marcel Drechsler, Xavier Strottner and Yann Sainty for their photograph Andromeda, Unexpected that captures a surprising discovery – a huge plasma arc next to the Andromeda Galaxy (M31). Scientists are now investigating the giant object in a transnational collaboration. It could be the largest such structure nearest to us in the Universe. The image will be on display alongside the winners of the other categories in the accompanying exhibition, opening at the National Maritime Museum on Saturday 16 September 2023.
