Cosmic Origins Spectrograph
The Cosmic Origins Spectrograph (COS) was installed on the Hubble Space Telescope (HST) in May 2009. COS is designed to perform high-sensitivity, medium- and low-resolution spectroscopy of astronomical objects in the 1150-3200 Å wavelength range. COS significantly enhances the spectroscopic capabilities of HST at ultraviolet wavelengths, providing observers with unparalleled opportunities for observing faint sources of ultraviolet light.
The primary science objectives of the mission are the study of the origins of large scale structure in the Universe, the formation and evolution of galaxies, the origin of stellar and planetary systems, and the cold interstellar medium.
More information and documentation on the Cosmic Origins Spectrograph can be found at CASA, the University of Colorado's Center for Astrophysics and Space Astronomy, Ball Aerospace, and the Experimental Astrophysics Group at the University of California - Berkeley.
