The annual competition ‘Insight Investment Astronomy Photographer of the Year‘ is organized by the Royal Observatory Greenwich and is now in its tenth year.

Over 4,200 photographs were submitted this year, but only these 25 images made it to the shortlist. These entries include a wide variety of subjects, from the sprawling Milky Way and storms on Saturn through to glacial tongues and the Northern Lights.

Rest your eyes on the astounding photographs below.

Located 1,270 light-years away, it’s one of the brightest nebulae (a star-forming region) in the night sky, and is visible with the naked eye on a clear night.
