Mayo Planetarium's “Cosmic Origins Spectrograph”: Ride Along on a Beam of Light!


Adult Enrichment / Nature -
2025 Fall Adult Catalog

Recommended for audiences ages 12+, this show explores the Hubble Space Telescope’s Cosmic Origins Spectrograph (C.O.S.), the nature of light, and the science of spectroscopy. Viewers will learn how quasars serve as background light sources, how different materials can be identified by their spectral signatures, and how matter cycles through the Milky Way and nearby galaxies. The experience concludes with a guided tour of the current night sky and the observable universe.
