The contest is organised by The World at Night and Global Astronomy Month along with The National Optical Astronomy Observatory.
The contest entries should be images, taken since January 1, 2016. They must be created in the “TWAN style” – showing both the Earth and the sky – by combining elements of the night sky (e.g., stars, planets, the Moon or celestial events) in the backdrop of a beautiful, historic, or notable location or landmark. This style of photography is called “landscape astrophotography”.
The contest theme, “Dark Skies Importance” has two categories: “Beauty of the Night Sky” and “Against the Lights”. Photographers can submit images to one or both categories.
