It's Dark Sky Week, which means it's time to turn out your lights at night and reduce light pollution so everyone can gaze at the stars. It's even tougher in the urban areas like Philadelphia to get it dark enough to really see the planets, but it doesn't hurt to try. Also on this weeks SkyTalk, learn about life on other planets and believe it or not, asteroids.
