Hubble Space Telescope The telescope would become the indispensable instrument for investigations of the cosmos. Bigger and better telescopes were built all over the world. Planets‚ stars‚ and nebulae which could not be seen by the naked eye were now being routinely noted and logged. Such is the case with the fantastic discoveries for which the Hubble Space Telescope has been responsible during the twentieth century. Had it not been for the creation of such a monumental piece of scientific machinery
