Details

Discover spectroscopy, the science of light, and learn how scientists study the Universe by deciphering clues hidden in light arriving from distant objects.

The Cosmic Origins Spectrograph (COS) is an instrument on the Hubble Space Telescope designed to analyze ultraviolet light from very distant, faint objects. COS allows us to learn about the origins of the large scale structure of the Universe, the cold interstellar medium, the formation and evolution of galaxies and the origin of stellar and planetary systems.

*Recommended for all audiences

There is no charge for our public programs, although donations of $1-$2 per attendee will be greatly appreciated to allow us to continue these public programs for our community.
