A Histоry оf Telescоpes A When you stаrt stаrgаzing with a telescope, two experiences typically ensue. First, you are astonished by the view—Saturn’s golden rings, star clusters glittering like jewelry on black velvet, galaxies aglow with gentle starlight older than the human species—and by the realization that we and our world are part of this gigantic system. Second, you soon want a bigger telescope.B Galileo, who first trained a telescope on the night sky 400 years ago, pioneered this two-step program. First, he marveled at what he could see. Galileo’s telescope revealed so many previously invisible stars that when he tried to map all of them in just one constellation—Orion—he gave up, confessing that he was “overwhelmed by the vast quantity of stars.” He saw mountains on the moon. He charted four bright satellites as they revolved around Jupiter like planets in a miniature solar system, something that critics of the sun-centered cosmology had dismissed as physically impossible. Evidently the Earth was a small part of a big universe, not a big part of a small one.C And soon, sure enough, Galileo went to work making bigger and better telescopes. Large light-gathering lenses were not yet available, so he concentrated on making longer telescopes, which produced higher magnifying powers. Subsequent observers took the design of glass-lensed, refracting telescopes to great lengths. In Danzig, Johannes Hevelius deployed a telescope 150 feet long; hung by ropes from a pole, it swayed in the slightest breeze. In the Netherlands, the Huygens brothers unveiled lanky telescopes that had no tubes at all. The objective lens was perched on a high platform in a field, while an observer up to 200 feet away aligned a magnifying eyepiece and peered through it. Such instruments offered fleeting glimpses of planets and stars that only aroused a burning desire to see more.D The reflecting telescope, pioneered by Isaac Newton, made it practical to gratify such desires. Mirrors required that only one surface be ground to gather and reflect starlight to a focal point, and since the mirror was supported from behind, it could be quite large without sagging under its own weight, as large lenses tended to do. William Herschel discovered the planet Uranus with a handmade reflecting telescope.
