"Astronomy Photographer of the Year 2023: Captivating Images and Discoveries"

A team of amateur astronomers has won the 2023 Astronomy Photographer of the Year competition with their photograph titled "Andromeda, Unexpected," featuring a massive plasma arc next to the Andromeda Galaxy. The image is a surprising discovery and could be the largest structure of its kind near us in the universe. Other winners include images of an ultra-deep stellar remnant, the Running Chicken Nebula, aurora, moon passing in front of Mars, the sun with a huge solar filament, and the rare phenomenon of Sprites. The winning images will be displayed in an exhibition at London's National Maritime Museum.
