In the northern hemisphere, BEST I had already been working since 2001. The Bochum Monitoring Telescope (BMT) was a 41-centimetre (16 in) Newton reflector, [11] known also as VYSOS 16, because it was used for the Variable Young Stellar Object Survey (VYSOS) in prominent Galactic star forming regions. It was equipped with a 3k x 2k CCD camera ...
In 1939 the 30-inch reflector was replaced with a Ross photographic telescope and in the years 1939 through 1951, Baker used the observatory's photographic telescope to help count the stars in the Milky Way and determine their distribution as part of Harvard University's Star Counting Circuit. [7]
The Arecibo radio telescope in 2019 A detailed view of the beam-steering mechanism. The triangular platform at the top was fixed, and the azimuth arm rotated beneath it. To the right was the Gregorian sub-reflector, and to the left was the remains of the 96-foot-long (29 m) line feed tuned to 430 MHz (destroyed by Hurricane Maria).
To make observations in the infrared spectrum, Webb must be kept under 50 K (−223.2 °C; −369.7 °F); otherwise, infrared radiation from the telescope itself would overwhelm its instruments. Its large sunshield blocks light and heat from the Sun, Earth, and Moon, and its position near the Sun–Earth L 2 keeps all three bodies on the same ...
The main telescope is a 400mm (16inch) Dobsonian reflector that was acquired in 2013. The observatory also houses a Victorian 0.25m (10 inch) Cooke refractor, with a focal length of 3.75 m. It was made in York in 1871 by Thomas Cooke and the optical components are of the highest quality. The telescope is actually older than the building.
While Kepler had cost US$640 million at launch, TESS cost only US$200 million (plus US$87 million for launch). [26] [27] The mission will find exoplanets that periodically block part of the light from their host stars, events called transits. TESS will survey 200,000 of the brightest stars near the Sun to search for transiting exoplanets. TESS ...
The agency's deputy acting director for astrophysics Michael Moore states that using both telescopes may ultimately save NASA $1.5 billion. [9] David Spergel estimated that using an NRO telescope would add about $100 million to WFIRST's cost, but would prefer to spend another $200 million for a coronagraph to improve its direct-imaging ...
The "Gemini North" telescope, officially called the Frederick C. Gillett Gemini Telescope [3] is located on Hawaii's Mauna Kea, along with many other telescopes. That location provides excellent viewing conditions due to the superb atmospheric conditions (stable, dry, and rarely cloudy) above the 4,200-metre-high (13,800 ft) dormant volcano.
