The Royal Observatory Greenwich has announced the winners of the Astronomy Photographer of the Year 15, during an award ceremony held Sept. 14.
This was the Royal Observatory Greenwich’s 15th year holding the contest, which garnered more than 4,000 submissions from 64 different countries for 2023. A shortlist of winning submissions was released in July, and many of those spectacular images have made a reappearance.
