The IRAM 30-meter telescope, located at 2850 meters altitude on Pico Veleta in the Spanish Sierra Nevada (Andalucia, Spain). The telescope is the world's premier single-dish facility for astronomical research in the millimeter wavelength range. [2] Both sites are at high altitude to reduce the absorption by water vapour in Earth's atmosphere.
The Origins Space Telescope would perform astrometry and astrophysics in the mid- to far-infrared range using a telescope with an aperture of 9.1 m (concept 1) or 5.9 m (concept 2). [8] [9] The telescope will require cryocooler systems to actively cool detectors at ~50 mK and the telescope optics at ~4 K. [8]
The Space Surveillance Telescope (SST) is a 3.5 m telescope that detects, tracks, and can discern small, obscure objects, in deep space with a wide field of view system. The SST mount uses an advanced servo-control technology, that makes it one of the quickest and most agile telescopes of its size.
The telescope is “one of the most ambitious projects ever undertaken,” one official said. ‘Origins of life’ may be revealed by world’s largest telescope, now under construction Skip to ...
ESO 3.6 m Telescope. The ESO 3.6 m Telescope is an optical reflecting telescope run by the European Southern Observatory at La Silla Observatory, Chile since 1977, with a clear aperture of about 3.6 metres (140 in) and 8.6 m 2 (93 sq ft) area. The telescopes uses the HARPS instrument and has discovered more than 130 exoplanets.
The telescope, built by Carl Zeiss AG, has a Ritchey-Chrétien configuration with a primary mirror with a diameter of 2.3 m. At the main f/8 Cassegrain focus, the corrected field of view is approximately one degree, with a plate scale of 1.17 arcsec/mm. It has an Altazimuth mount. The telescope is housed in a tower 35 meters away from the ...
Zooming in on a portion of the Euclid telescope's map 600 times reveals the galaxies within the cluster Abell 3381, located 470 million light-years away from Earth.
