Figure 2-25 NASA’s Great Observatories Space Telescopes Orbiting above most of Earth’s obscuring atmosphere, space observatories can be configured to capture light across a wide range of wavelengths. From shortest wavelength light across to the longer wavelengths of light, this illustration shows the Compton Gamma Ray Observatory (CRGO), the Chandra X-ray Observatory, the Hubble Space Telescope (HST), and the Spitzer Space Telescope (SST).
