American photographer Ryan Imperio has been named overall winner in the Astronomy Photographer of the Year competition.
Imperio's work, Distorted Shadows of the Moon's Surface Created by an Annular Eclipse, was shot in Texas during a solar eclipse last year.
It is a composite of more than 30 separate images of the Sun and captures the optical illusion - known as Baily's beads - when sunlight shines through mountains and other topographical features of the Moon.
