The University of Arizona's College of Optical Sciences has been awarded a multi-million dollar contract by the Association of Universities for Research in Astronomy, or AURA, to polish the primary mirror for the Advanced Technology Solar Telescope, or ATST.
Many amateur astronomers point their Orion telescopes towards the International Space Station every night. Earlier this month, British astronomer Martin Lewis took numerous images of the International Space Station using his home made telescope and a web cam.
Metal mirrors made with extremely high precision and exactly positioned are the key elements of modern telescopes.
After 3 years and $10,000 worth of restoration costs, Albert Einstein's long-lost telescope will be put on display at the Hebrew University in Jerusalem, an institution the theorist helped start.
New historical evidence suggests the telescope may have been invented in Spain, not the Netherlands or Italy as scientists once thought.
Scientists working at NASAâ€™s Goddard Space Flight Center in Greenbelt, Md., have concocted an innovative recipe for giant telescope mirrors on the Moon. To make a mirror that dwarfs anything on Earth, just take a little bit of carbon, throw in some epoxy, and add lots of lunar dust.
A telescope, designed to aid the observation of remote objects, collects some form of electromagnetic radiation (such as visible light). The Netherlands developed the first known practical telescope in the 17th century. The term "telescope" was termed in order to describe Galileo's instruments in 1611. However, Galileo was not the inventor of the telescope. It was Hans Lippershey, Zacharias Janssen, and Jacob Metius who are credited with the creation of the telescope. In 1668, Isaac Newton...
Telescope -- A telescope is an instrument composed of one or more lenses or mirrors to gather and focus electromagnetic radiation. Telescopes increase the observed angular size of objects, as well as their apparent brightness. The largest telescopes are used in astronomy. A telescope was first turned on the sky by Galileo Galilei, the Italian scientist. (Telescopes used for non-astronomical purposes may be called "transits," "monoculars," "binoculars," "camera lenses," or "spyglasses".)...
Active Optics -- Active optics is a relatively new technology for astronomic telescopes. Most modern telescopes are reflectors, with the primary element being a very large mirror. Historically, a fixed weight-to-diameter relation was used to build these mirrors, limiting their maximum diameter to 5 or 6 meters (200 or 230 inches), like in the Palomar Observatory. A new generation of telescopes uses instead very thin mirrors, uncapable of sustaining themselves. Instead, an array of...

Credit: Denys/Wikipedia (CC BY-SA 3.0) The Subaru Telescope is a 26.9-foot (8.2m) telescope located at the Mauna Kea Observatory on the Big Island of Hawaii and operated by the National Astronomical Observatory of Japan (NAOJ). It had the largest primary mirror in the world until 2005. This is a reflecting telescope with a large field of view--called a Ritchey-Chretien--which has a primary mirror and a secondary...
