A year ago I had the privilege to visit the beautiful island of La Palma to attend the Starlight Conference.
Can you pick me out in the crowd?
At the conference the Declaration in Defense of the Night Sky and the Right to Starlight was adopted by the international group of attendees. The basic idea behind it is that everyone should have the right to see and enjoy the night sky and that obtrusive light must be controlled. Why? It is a part of our heritage, nature depends on a 24-hour day/night cycle, our health may depend on it, and of course it is good for astronomy too.
Tomorrow, April 20th has been declared The World Night in Defence of the Starlight. Be sure to visit the link, watch the videos and act to preserve the night sky for everyone.
