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 . ...
