The 2013 International Earth and Sky Photo Contest

The 2013 International Earth and Sky Photo Contest

The Global Astronomy Month in April 2013 brings the 4th International Earth and Sky Photo Contest on Dark Skies Importance. Coordinated by TWAN the contest is open to anyone of any age, anywhere around the world.

From now through Earth Day, April 22, an on-line “Earth and Sky” photo contest is open for submission by any photography enthusiasts of any age from around the world. International projectsThe World at Night and Global Astronomy Monthalong 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. In 2012 participants from about 50 countries submitted a wonderful collection of nightscape images. The contest news was broadcasted by major science news media world-wide and the winning images were widely promoted. With the growing 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.

Submitted photographs 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''. This is similar to general "Nightscape Photography" but with more attention to the sky, astronomical perspectives, and celestial phenomena.

The contest theme, “Dark Skies Importance,” has two categories: “Beauty of the Night Sky” and “Against the Lights.” Photos submitted to the contest should aim to address either category: either to impress people on how important and amazing the starry sky is or to impress people on how bad the problem of light pollution has become. Both categories illustrate how light pollution affects our lives. Photographers can submit images to one or both categories. The contest organizers encourage participants to view examples of such photos by the winners in the previous years: the 2012 winners2011, and 2010.
Winners this year will be announced in the first week of May.
