Astronomy Photographer of the Year is an annual photography competition and exhibition held at the National Maritime Museum in Greenwich.

Every year, we're treated to spellbinding images of the night sky, from dazzling aurorae to close-up views of distant galaxies.

But there can only be one Astronomy Photographer of the Year.
