Relative positions of each unit telescope in a single GOTO system. The UTs are ASA H400 Newtonian telescopes, each with an aperture of 400mm and a focal length of 960mm (f/2.4). [2] Attached to each telescope is a focuser, filter wheel, and a Finger Lakes Instrumentation (FLI) ML50100 camera, [2] based on the Onsemi KAF-50100 CCD sensor. [6]
The Monitor of All-sky X-ray Image (MAXI) is an X-ray telescope mounted on the International Space Station since 2009. The instrument uses wide field of view X-ray detectors to perform a sky survey , measuring the brightness of X-ray sources every 96 minutes (one ISS orbit).
Astronomers using the Hubble Space Telescope and the Very Large Telescope have made precise tests of general relativity on galactic scales. The nearby galaxy ESO 325-G004 acts as a strong gravitational lens, distorting light from a distant galaxy behind it to create an Einstein ring around its centre. By comparing the mass of ESO 325-G004 (from ...
SPHEREx will use a spectrophotometer to perform an all-sky survey that will measure near-infrared spectra from 0.75 to 5.0 micrometers. It will employ a single instrument with a single observing mode and no moving parts to map the entire sky (in 96 different color bands, far exceeding the color resolution of previous all-sky maps [4]) four times during its nominal 25-month mission; the crucial ...
In 2013, NASA reactivated the WISE telescope to search for near-Earth objects (NEO), such as comets and asteroids, that could collide with Earth. [12] [13] The reactivation mission was called Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE). [13] As of August 2023, NEOWISE was 40% through the 20th coverage of the full sky ...
HTRU – A pulsar and radio transients survey of the northern and southern sky using the Parkes Radio Telescope and the Effelsberg telescope. Gamma-ray Fermi Gamma-ray Space Telescope, formerly referred to as the "Gamma-ray Large Area Space Telescope (GLAST)." 2008–present; the goal for the telescope's lifetime is 10 years. Multi-wavelength ...
The Multi-Unit Spectroscopic Explorer (MUSE) is an integral field spectrograph installed at the Very Large Telescope (VLT) of the European Southern Observatory (ESO). [1] [2] [3] It operates in the visible wavelength range, [1] and combines a wide field of view with a high spatial resolution and a large simultaneous spectral range (480-930 nm). [4]
By using a telescope which flew at over 42,000 meters high, it was possible to reduce the atmospheric absorption of microwaves to a minimum. This allowed massive cost reduction compared to a satellite probe, though only a tiny part of the sky could be scanned. The first was a test flight over North America in 1997.
