What Does FOS Stand For?
FOS stands for Faint Object Spectrograph
Faint Object Spectrograph (FOS) is an astronomical instrument designed to analyze the light spectra of faint celestial objects. By dispersing light into its component colors, FOS enables scientists to study the chemical composition, temperature, density, and motion of these distant objects, enhancing our understanding of the universe. This device has been utilized in various space telescopes, most notably the Hubble Space Telescope, to capture critical data on a wide range of astronomical phenomena.
