2009 is the International Year of Astronomy

The New Scotsman reminds us all that:

A FIFTH of the world's population can no longer see the Milky Way with the naked eye due to artificial lights blocking out the view of the stars.
This year, which is International Year of Astronomy, a new project is taking place to try to improve the visibility of the stars.

Campaigners at the Dark Skies Awareness project will be lobbying local authorities and members of the public to turn off lights in built-up areas at night.

Malcolm Smith, an astronomer at the Cerro Tololo Inter-American Observatory in Chile, wrote about the importance of the project in the journal Nature.

He said: "Over the past six decades, professional and amateur astronomers have been pioneering efforts to curb light pollution to protect the viability of their observatories.

"During the 2009 International Year of Astronomy, particularly through the Dark Skies Awareness project, astronomers can find allies in a common cause to convince authorities and the public that a dark sky is a valuable resource for everyone." Mr Tololo explains that turning lights off at night has benefits beyond improving the view of the stars.

"Reducing the number of lights on at night could help conserve energy, protect wildlife and benefit human health," he said.

"The most persuasive arguments for lighting control are economic ones. Estimates by the International Dark-Sky Association, based on work from satellite images, show that cities needlessly shine billions of pounds worth of light directly into the sky each year.

"As education on these issues improves, some cities are now realising the benefits of controlling such energy waste through better-quality lighting, thereby reducing dangerous glare and confusing lighting clutter."
