... Credit: STS-82 Crew , STScI , NASA Explanation: Why put observatories in space? Most telescopes are on the ground. ... The trouble is that Earth-bound telescopes must look through the Earth's atmosphere . First, the Earth's atmosphere blocks out a broad range of the electromagnetic spectrum , allowing a narrow band of visible light to reach the surface. ... By orbiting above the Earth's atmosphere, the Hubble Space Telescope, pictured above , can get clearer images. ... Walking in Space . ...

The Hubble orbiting telescope. The Earth's atmosphere, while transparent to visible light, absorbs most "electromagnetic radiations" which belong to the same family as light: parts of the infra-red (IR) and all of the ultra-violet (UV), X-rays and gamma rays. ... The Hubble telescope , in low Earth orbit, overcomes such limitations, in the visible range and in part of the UV. ... Some satellites specialize in observing the Sun, such as the Japanese Yohkoh and NASA's SOHO . ...
