1611 — Johannes Kepler describes the optics of lenses (see his books Astronomiae Pars Optica and Dioptrice), including a new kind of astronomical telescope with two convex lenses (the 'Keplerian' telescope). 1616 — Niccolo Zucchi claims at this time he experimented with a concave bronze mirror, attempting to make a reflecting telescope.
Notes on Hans Lippershey's unsuccessful telescope patent in 1608. The first record of a telescope comes from the Netherlands in 1608. It is in a patent filed by Middelburg spectacle-maker Hans Lippershey with the States General of the Netherlands on 2 October 1608 for his instrument "for seeing things far away as if they were nearby." [12] A few weeks later another Dutch instrument-maker ...
Cox built his first telescope, a 6-inch reflector, at age 16 and four years later had completed a 10-inch reflector as well. [1] With Lou Lojas, Ed Hanna and Carl Groswendt, he founded the Amateur Telescope Makers of New York which became the Optical Division of the New York Amateur Astronomers Association in 1937.
Lowell Observatory owns and operates the Lowell Discovery Telescope (LDT, formerly the Discovery Channel Telescope) located near Happy Jack, Arizona. This 4.3-meter reflecting telescope is the fifth-largest telescope in the contiguous United States and one of the most powerful in the world, thanks to a unique housing that can accommodate up to ...
The telescope became operational in mid-1957, in time for the launch of the Soviet Union's Sputnik 1, the world's first artificial satellite. The telescope was the only one able to track Sputnik's booster rocket by radar; [21] [22] first locating it just before midnight on 12 October 1957, eight days after its launch. [23] [24]
A space telescope (also known as space observatory) is a telescope in outer space used to observe astronomical objects. Suggested by Lyman Spitzer in 1946, the first operational telescopes were the American Orbiting Astronomical Observatory , OAO-2 launched in 1968, and the Soviet Orion 1 ultraviolet telescope aboard space station Salyut 1 in 1971.
Terrestrial Planet Finder – Infrared interferometer concept A simulated view of the coronagraph for Terrestrial Planet Finder. (Courtesy NASA/JPL-Caltech) The Terrestrial Planet Finder (TPF) was a proposed project by NASA to construct a system of space telescopes for detecting extrasolar terrestrial planets.
Zacharias Janssen; also Zacharias Jansen or Sacharias Jansen; 1585 – pre-1632 [1]) was a Dutch spectacle-maker who lived most of his life in Middelburg.He is associated with the invention of the first optical telescope and/or the first truly compound microscope, but these claims (made 20 years after his death) may be fabrications put forward by his son.
