What Does COS Stand For?
COS stands for Cosmic Origins Spectrograph
The Cosmic Origins Spectrograph (COS) is a scientific instrument aboard the Hubble Space Telescope designed to analyze the ultraviolet light from astronomical objects. By capturing and dispersing light into its component wavelengths, COS enables researchers to study the chemical composition, physical properties, and dynamics of celestial phenomena, including stars, galaxies, and intergalactic medium. Its high sensitivity and resolution enhance our understanding of the universe's formation and evolution, particularly in relation to cosmic structures and the origins of life.
