"Submission is open until April 22. Images must be taken since January 1, 2014. The winners will be announced in late May.
The on-line “Earth and Sky” photo contest is open for submission by any photography enthusiasts of any age from around the world. International projects The World at Night and Global Astronomy Month along with the National Optical Astronomy Observatory are the organizers of the Earth and Sky Photo Contest. The contest was founded by TWAN and Dark Skies Awareness project in 2008 as a regional program. It was expanded to an international effort in 2009 during the International Year of Astronomy. The contest news is usually broadcasted by major science and art news media world-wide and the winning images were widely promoted. With the growing impact of TWAN on both photography and astronomy communities along with the efforts of Astronomers Without Borders (AWB), the organization behind the Global Astronomy Month, the Earth and Sky Photo Contest will have an even larger feedback this year."
