A test unit for the "NIRCam" instrument that will fly aboard the James Webb Space Telescope has arrived at NASA's Goddard Space Flight Center in Greenbelt, Md and has been placed in a clean room for a year's worth of tests.
NASA's James Webb Space Telescope has passed its most significant mission milestone to date, the Mission Critical Design Review, or MCDR.
WASHINGTON, April 28 /PRNewswire-USNewswire/ -- NASA's James Webb Space Telescope has passed its most significant mission milestone to date, the Mission Critical Design Review, or MCDR. This signifies the integrated observatory will meet all science and engineering requirements for its mission.
The Large Binocular Telescope (LBT) partners in Germany, the U.S.A. and Italy are pleased to announce that the first of two new innovative near-infrared cameras/spectrographs for the LBT is now available to astronomers for scientific observations at the telescope on Mt. Graham in south-eastern Arizona.
The James Webb Space Telescope reached a mission-readiness landmark today when its first primary mirror segment was cryo-polished to its required prescription as measured at operational cryogenic temperatures.
GREENBELT, Md., March 2 /PRNewswire-USNewswire/ --The James Webb Space Telescope reached a mission-readiness landmark today when its first primary mirror segment was cryo-polished to its required prescription as measured at operational cryogenic temperatures.
In ancient mythological times reflective surfaces like shiny metals and mirrors were thought to be magical and credited with the ability to look into the future.
HUNTSVILLE, Ala., Jan. 7 /PRNewswire-USNewswire/ -- In ancient mythological times reflective surfaces like shiny metals and mirrors were thought to be magical and credited with the ability to look into the future. NASA is using mirrors to do just the opposite -- look into the past.
A key tool to unlocking the secrets of the universe will soon be unveiled by Spain on the Canary Islands.
ESOâ€™s Very Large Telescope â€” Europeâ€™s flagship facility for ground-based astronomy â€” has been equipped with the first of its second generation instruments: X-shooter.
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...
Very Large Telescope -- The Very Large Telescope (VLT) consist of four optical telescopes that have 8.4 meter aperture. The VLT is a project of the European Southern Observatory organization. It is located at the Paranal Observatory on Cerro Paranal, a 2,635-m high mountain in the Atacama desert in northern Chile. The VLT consists of a cluster four of large telescopes, and an interferometer (VLTI) which will be used to resolve fine features. The telescopes have been named after the...
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".)...
Adaptive Optics -- Adaptive optics is a technology to improve the performance of Earth-based telescopes, reversing the effect of atmospheric distortions. When light from a star or another astronomical object enters the Earth's atmosphere, the different temperature layers and different wind speeds distort and move the image in various ways (see seeing for a proper discussion). The net result is that an 8 meters or 10 meters telescope (like the VLT or Keck), while theoretically capable...
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...
