The Orbiting Hubble Space Telescope
Space Telescope Scientific Institute
Hubble Space Telescope (HST) is the largest orbiting public
in history. Its 2.4 metre diameter reflecting mirror and its perch
atmosphere allow it to create exceptionally sharp images.
launched in 1990, HST optics were repaired to their intended
accuracy in 1993 by the first of several regular servicing missions.
Astronomers using HST continue to make numerous monumental scientific
new estimates of the age of our universe,
previously unknown galaxies,
evidence of massive black holes in the centres of galaxies,
previously unknown moons,
and a better understanding of
physical processes in our universe.
