The Hubble Space Telescope is a cooperative program of the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA).
HST’s current complement of science instruments includes three cameras, two spectrographs, and fine guidance sensors (primarily used for astrometric observations). These instruments produce high resolution images of astronomical objects. Ground-based telescopes seldom provide resolution better than 1.0 arc-seconds; HST’s resolution is about 10 times better, or 0.1 arc-seconds.
