Telescope

A telescope is an instrument that aids in the observation of remote objects by collecting electromagnetic radiation (such as visible light). The first known practical telescopes were invented in the Netherlands at the beginning of the 1600s (the 17th century), using glass lenses. They found use in terrestrial applications and astronomy.

Under the supervision of George Ellery Hale, and through grants from the Carnegie Institution of Washington, the Mount Wilson 60-inch telescope is completed and sees "first light." It is the world's largest telescope, and with the exceptionally calm and stable atmosphere above the Los Angeles basin, astronomers can see fainter and more distant objects than ever before

The telescope was the first instrument to extend human senses, revolutionising our view of the heavens and our place in the world. But, as Richard Dunn explains, the first effects of this technological marvel were felt much closer to home

what we are seeing is the evolution of telescopes away from the concrete and steel that forms the antennas and into the world of supercomputing, says Professor Brian Boyle, CSIRO's SKA director.

Most people are only familiar with optical telescopes, that is telescopes that detect radiation in the visible spectrum. BUT Since gamma-rays, x-rays, radio waves, infrared waves and ultraviolet waves are also forms of electromagnetic radiation, telescopes can also be designed to detect those waves.

NASA's James Webb Space Telescope is a large, infrared-optimized space telescope that will be the premier observatory of the next decade. It will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System.

From the dawn of humankind to a mere 400 years ago, all that we knew about our universe came through observations with the naked eye. Then Galileo turned his telescope toward the heavens in 1610. The world was in for an awakening.

Four centuries ago, stories issued from the Netherlands describing the invention of a twin-lens device for seeing at a distance – the telescope. Though it began its life as no more than a low-power spyglass, it quickly evolved into a high-magnification precision optical instrument, capable even of viewing Jupiter’s moons.

The $1.5 billion Hubble rocketed to space aboard the space shuttle Discovery on April 24, 1990. It's named after Edwin Hubble, a pioneering American astronomer who furthered our understanding of other galaxies and demonstrated that the universe is continually expanding.

From 1616, Galileo tried to apply his knowledge of the satellites of Jupiter to the determination of longitude at sea. In order to ensure observation at sea, the Tuscan arsenal made for Galileo a headgear which had a telescope attached. Around this time, he also designed a brass 'Jovilabe', a computing device for prediction positions of the satellites.

In July 1609, Galileo was in Venice, when he heard of an invention that allowed distant objects to be seen as distinctly as if they were nearby. In October 1608, a Flemish spectacle-maker by the name of Hans Lipperhey had already applied for a patent (which was refused).
