 2% for this week. 9.42, Metro is taking you on a journey through the universe. You can get a glimpse at exploding stars, nebula, even black holes when you ride Metro Rail. It's all made possible through a partnership between the Smithsonian and Metro's Art in Transit program. As part of this show, images from the Chandra X Ray Observatory will be displayed at six Metro stations through October. We're talking Lafonte Plaza, Metro Center, Gallery Place, Farragut North, Noma, and Crystal City.
