The James Webb Space Telescope ( JWST) is a space telescope designed to conduct infrared astronomy. As the largest telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant, or faint for the Hubble Space Telescope. [10] This enables investigations across many fields of ...
The W. M. Keck Observatory is an astronomical observatory with two telescopes at an elevation of 4,145 meters (13,600 ft) near the summit of Mauna Kea in the U.S. state of Hawaii. Both telescopes have 10 m (33 ft) aperture primary mirrors, and, when completed in 1993 (Keck I) and 1996 (Keck II), they were the largest optical reflecting ...
List of largest optical refracting telescopes. The Grande Coupole for the double refractor of Meudon, with roughly 83 cm (33 in) and 62 cm (24 in) aperture lenses on the same mounting, and making its debut in 1891. Refracting telescopes use a lens to focus light. The Swedish 1-m Solar Telescope, with a lens diameter of 43 inches, is technically ...
List of telescope types working outside the optical spectrum. Atmospheric Cherenkov telescope used to detect gamma rays. Infrared telescope. Radio telescope. Submillimeter telescope. Ultraviolet telescope (see also Ultraviolet astronomy) X-ray telescope (see also X-ray astronomy ) Wolter telescope.
This is a list of large optical telescopes.For telescopes larger than 3 meters in aperture see List of largest optical reflecting telescopes.This list combines large or expensive reflecting telescopes from any era, as what constitutes famous reflector has changed over time.
A telescope is a device used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. [1] Originally it was an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects – an optical telescope. Nowadays, the word "telescope" is defined as a wide range of ...
