Our Goals

●► To help people rediscover their place in the Universe through the day- and night-time sky, and thereby engage a personal sense of wonder and discovery beyond IYA2009.

●► To help the citizens of the world acquire heightened awareness about light pollution, and thereby preserve and protect the nighttime environment and our heritage of dark skies.

Celebrating Clear Skies

In this action scene, red night vision lights, green laser pointers, tripods and telescopes in faint silhouette surround intrepid sky gazers embarked on the 10th annual Iran Messier Marathon. Completing the marathon requires viewing all 110 objects in 18th century French astronomer Charles Messier's catalog in one glorious dusk-to-dawn observing run. As daunting as it sounds, there are often favourable weekend dates for northern hemisphere marathoners to complete the task that fall on nearly moonless nights near the spring equinox. With the Milky Way as a backdrop, this group of about 150 astronomy enthusiasts conducted their 2011 Messier Marathon on April 2/3, 2011 from the desert area of She Qaleh, in eastern Iran.      Image Credit: Babak Tafreshi (TWAN)

Reduce light pollution & save energy.

Once a source of wonder—and one half of the entire planet’s natural environment—the star-filled nights of just a few years ago are vanishing in a yellow haze. Human-produced light pollution not only masks our view of the stars; poor lighting threatens astronomy, disrupts ecosystems, affects human circadian rhythms, and wastes energy.

The problem of light pollution is easily remedied. In general, good lighting uses only the amount of light necessary for a specific purpose, and that light is directed properly. Lights allowing no illumination above the horizontal plane of the fixture and mounted at the proper height to do their job while avoiding glare and light trespass are the ideal.
