educational programs presented by the planetarium, the staff offers Cosmic Concerts on the first Friday nights of each month. The shows combine music (usually rock, pop or classical) with a multi-colored laser light show and video projected on the dome, interspersed with special effects and cosmic images of galaxies, nebulas, and pulsars. The museum also sells diffraction glasses which can enhance the viewing experience. The audio is recorded and played back digitally on the planetarium's 18,000-watt sound system. In early 2010, the aging laser light system began to require so much water to cool the equipment that the staff discontinued the Cosmic Concerts until the new laser projection system and multicolored LED lighting system were installed in late summer.
