Scope and Contents From the Sub-Series: The Advanced X-ray Astrophysics Facility was a telescope using x-rays to see the “empty” space between stars and galaxies that is actually filled with superhot gas. The AXAF was proposed to produce sharp, magnified images in x-rays that complement those made by the Hubble Space Telescope in visible light. Renamed the Chandra X-ray Observatory CXO, the telescope was launched on the space shuttle Columbia in 1999. It is known as one of the Great Observatories. In the early...

In the mid-1980s, Arthur F. Davidsen was the Principal Investigator for developing a second generation spectrograph for the Hubble Space Telescope, called the Decade Imaging Spectrograph and Camera (DISC). DISC was designed to exceed the capabilities of the Faint Object Spectrograph and the Faint Object Camera, but was not approved for installation on the Hubble Space Telescope.
