CAFE (Calar Alto Fibre-fed Echelle spectrograph) installed on the Calar Alto Observatory's 2.2-metre telescope in 2014, and the CARMENES mounted on the 3.5-metre telescope in 2016. EXPRES is a third generation radial velocity spectrograph that is planned to be installed on the Lowell Discovery Telescope. Space based detectors :
Positioning an optical telescope in space eliminates the distortions and limitations that hamper that ground-based optical telescopes (see Astronomical seeing), providing higher resolution images. Optical telescopes are used to look at planets , stars , galaxies , planetary nebulae and protoplanetary disks , amongst many other things.
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]
Composite image of the GOODS-South field, result of a deep survey using two of the four giant 8.2-metre telescopes composing ESO's Very Large Telescope Gamma-ray pulsars detected by the Fermi Gamma-ray Space Telescope. An astronomical survey is a general map or image of a region of the sky (or of the whole sky) that lacks a specific ...
Slow motion movie of the image seen at a telescope when looking at a star at high magnification (negative images). The telescope used had a diameter of about 7r 0 (see definition of r 0 below, and example simulated image through a 7r 0 telescope). The star breaks up into multiple blobs (speckles) -- entirely an atmospheric effect.
TOLIMAN will focus on stars within 10 parsecs (32.6 light years) of the Sun. [2] The telescope, still under construction, [3] is expected to be launched into low Earth orbit no earlier than 2024. [4] The mission will involve scientists of the University of Sydney , Saber Astronautics in Australia, Breakthrough Initiatives , and NASA's Jet ...
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 ...
A fine guidance sensor (FGS) is an instrument on board a space telescope that provides high-precision pointing information as input to the telescope's attitude control systems. Interferometric FGSs have been deployed on the Hubble Space Telescope; a different technical approach is used for the James Webb Space Telescope's FGSs.
