单词	Hubble Space Telescope
释义	Hubble Space Telescope A telescope used to take pictures from space, avoiding the difficulties arising from the earth's atmosphere. These pictures give important information on many aspects of astronomy and cosmology. The Hubble Space Telescope (named after Edwin Hubble) was launched in 1990 by the National Aeronautics and Space Administration (NASA) of the USA. Since a defective mirror was corrected in 1993 the scientific results obtained have included: (1) measurements of the Hubble constant and hence the age of the universe; these measurements indicate that the big-bang theory may be in need of modification; (2) evidence for a black hole at the centre of a galaxy; (3) evidence that in several cases a quasar is not surrounded by a galaxy; (4) pictures of fragments of the comet Shoemaker-Levy 9 crashing into Jupiter; (5) pictures of some of the most distant galaxies known, which indicate the need for changes in theories of the evolution of galaxies.
