It is, however, very expensive. Nearly half of all the effort that the human race has put into telescopes over all of history has gone into that one telescope, the Hubble. In part, that is because it got tangled up in the politics of the Space Shuttle, back in the 1970's. It is a big advantage to have an optical telescope above the atmosphere, since the atmosphere causes "seeing" (twinkling) of the stars. The Hubble is therefore the best telescope there is for making pictures at high magnification. The Hubble is much smaller than a number of ground-based telescopes nowdays, and that makes it relatively insensitive for very faint objects. Also, it has a very specific set of instruments that are not easily changed, so it can do some types of observations but not others. The Hubble has looked at hundreds of thousands of celestial bodies. See the website. The Hubble Space Telescope is a wonderful thing. It is, however, very expensive.

This really distorts the image of whats being viewed and limits the distance we can see via the telescope. On the other hand, the Hubble has no air to contend with.....just space and whatever it holds. The distance and sharpness of items viewed by the Hubble telescope is practically limitless.
