John Keller is an Astronomer and director of Fiske Planetarium at the University of Colorado. We'll discuss a green comet that should be visible, at least with binoculars and maybe with the naked eye, at night for the next few weeks. We'll also talk about the discovery of a new planet that could theoretically have conditions favorable to life.
