Be sure to participate in Earth Hour Saturday, March 29. From 8:00 to 9:00 p.m everyone is being asked to turn out their lights for the hour. Why? Turning off unneeded lights will save energy and make a statement towards fighting global warming. Turning off outdoor lights will also give everyone (including those that work at observatories) the opportunity to have a darker sky from which to enjoy (or study) the stars.
March 29th also kicks off National Dark-Sky Week which runs until April 4. This is a great time to see the nighttime sky and learn what can be done to preserve it. Visit the website of the International Dark-Sky Association, THE source on nighttime lighting, to learn about what can be done each and every week of the year.
