Largest does not always equate to being the best telescopes, and overall light gathering power of the optical system can be a poor measure of a telescope's performance. Space-based telescopes, such as the Hubble Space Telescope, take advantage of being above the Earth's atmosphere to reach higher resolution and greater light gathering through ...
The Gran Telescopio Canarias (GranTeCan or GTC) is a 10.4 m (410 in) reflecting telescope located at the Roque de los Muchachos Observatory on the island of La Palma, in the Canary Islands, Spain. It is the world's largest single-aperture optical telescope. [1] Construction of the telescope took seven years and cost €130 million.
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.
In the predawn hours of September 20th, 2017, the cavernous hangar doors of the Richard F. Caris Mirror Lab at the University of Arizona slowly swung open and the first of seven gargantuan mirrors ...
The second generation Near Infrared Camera works with the Keck Adaptive Optics system to produce the highest-resolution ground-based images and spectroscopy in the 1–5 micrometers (μm) range. Typical programs include mapping surface features on Solar System bodies, searching for planets around other stars, and analyzing the morphology of ...
The Giant Magellan Telescope (GMT) is a ground-based, extremely large telescope currently under construction at Las Campanas Observatory in Chile's Atacama Desert.With a primary mirror diameter of 25.4 meters, it is expected to be the largest Gregorian telescope ever built, observing in optical and mid-infrared wavelengths (320–25,000 nm).

On a mountaintop in northern Chile, the Vera C. Rubin Observatory, which holds the largest digital camera in the world, is preparing to power up. Telescope with world’s largest digital camera ...
Construction was set to begin Monday on the Square Kilometer Array, the largest radio telescope ever, which will scan the skies for aliens and try to see to the very edge of the universe.
