Assessing and ending light pollution

Light pollution is a major problem for astronomers in most if not all countries (see map) . But for the International Year of Astronomy this may change with the following initiative.

Globe at Night allows astronomers to easily assess the phenomenon with a series of charts. By watching the Orion Constellation, it is simple to know if your local sky is polluted or not.

Significant changes have been reached in the past few years in local areas but we now need a global initiative to decrease the amounts of lights of our cities and suburbia.

For more, check out the International Dark Sky Association’s website. Their goals are :

Stop the adverse effects of light pollution, including;

* Energy waste, and the air and water pollution caused by energy waste
* Harm to human health
* Harm to nocturnal wildlife and ecosystems
* Reduced safety and security
* Reduced visibility at night
* Poor nighttime ambience; and

Raise awareness about light pollution, its adverse effects, and its solutions; and

Educate about the values of quality outdoor lighting.
