A zenith telescope is a type of telescope that is designed to point straight up at or near the zenith. They are used for precision measurement of star positions, to simplify telescope construction, or both. A classic zenith telescope, also known as a zenith sector employs a strong altazimuth mount, fitted with levelling
A zenith telescope is a type of telescope designed to point straight up at or near the zenith, and used for precision measurement of star positions, to simplify telescope construction, or both. The NASA Orbital Debris Observatory and the Large Zenith Telescope are both zenith telescopes, since the use of liquid mirrors meant these telescopes ...
An astronomical instrument is a device for observing, measuring or recording astronomical data.They are used in the scientific field of astronomy, a natural science that studies celestial objects and the phenomena that occur in the cosmos, with the object of explaining their origin and evolution over time.
NASA's James Webb Space Telescope (JWST) has captured photos of one of the earliest supernovas ever seen, with features appearing like grains and knots found in a cut of wood. "Once upon a time ...
The Large Zenith Telescope (LZT) was a 6.0-meter diameter liquid-mirror telescope located in the University of British Columbia's Malcolm Knapp Research Forest, about 70 km (43 mi) east from Vancouver, British Columbia, Canada (north from Maple Ridge). It was one of the largest optical telescopes in the world, but still quite inexpensive. The ...
EGRET – (telescope) Energetic Gamma Ray Experiment Telescope, another name for the Compton Gamma Ray Observatory; EGS – Extended Groth Strip, a deep field; EHB – (celestial object) extreme horizontal branch, a type of hot, evolved star; EJASA – (publication) Electronic Journal of the Astronomical Society of the Atlantic
Visible-light astronomy has existed as long as people have been looking up at the night sky, although it has since improved in its observational capabilities since the invention of the telescope, which is commonly credited to Hans Lippershey, a German-Dutch spectacle-maker, [1] although Galileo played a large role in the development and ...
A second experiment, called Ozma II, was conducted with a larger (300 feet (91 m)) telescope at the same observatory by Patrick Palmer and Benjamin Zuckerman, who intermittently monitored 670 nearby stars for about four years (1972–76). [6] They examined a 10 MHz bandwidth with 52 kHz resolution and a 625 kHz bandwidth with 4 kHz resolution.
