Future prospects for spectroscopic and direct work - Optical and UV

Abstract

A description of the main features and proposed instrumentation of the 2.4 m Space Telescope is given. Highlights of work that can be planned on active nuclei of galaxies, QSOs, and BL Lac objects are briefly outlined, involving spectroscopy over wavelengths from 1200 A to 1 mm, direct imaging with 0.1 sec resolution, and the capability for 0.1 sec resolution along the spectrograph slit. The resolution, the much reduced sky background, and the full wavelength coverage also make possible important observations relevant to cosmology.
