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.
