Astronomy Photographer of the Year is the largest international competition of its kind. Organised by the Royal Observatory Greenwich and sponsored by Insight Investment, the competition receives entries from photographers all around the world. It annually showcases the best space photography from a global community of astrophotographers.

I took this image at my favourite astrophotography field and it shows one of the most vibrant, colourful nebulas in space. You can see many interesting deep-sky objects such as Rho Ophiuchi, the triple star surrounded by the blue reflection nebula IC 4604, at top-left, the red supergiant star Antares and one of the closest globular clusters to the Solar System, M4, to the right.
