Multiple mirror telescopes that are on the same mount and can form a single combined image are ranked by their equivalent aperture. Fixed altitude telescopes (e.g. HET) are also ranked by their equivalent aperture. All telescopes with an effective aperture of at least 3.00 metres (118 in) at visible or near-infrared wavelengths are included.
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 ...
Unlike most Earth viewers, WorldWide Telescope supports many different map projections including Mercator, Equirectangular and Tessellated Octahedral Adaptive Subdivision Transform (TOAST). There are also map layers for seasonal, night, streets, hybrid and science oriented Moderate-Resolution Imaging Spectroradiometer (MODIS) imagery. The new ...
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. ... A prime example is the ...
Zooming In on the Andromeda Galaxy, also known as Gigapixels of Andromeda, is a 2015 composite photograph of the Andromeda Galaxy produced by the Hubble Space Telescope. It is 1.5 billion pixels in size, and is the largest image ever taken by the telescope. [1] At the time of its release to the public, the image was one of the largest ever ...
[image needed] February–March 1959 Vanguard 2: First attempt of a scanner, in which a single photocell mounted at the focus of telescope would scan Earth due to the satellite movement; resulting images were poor. [16] August 14, 1959 Explorer 6: First image of Earth from orbit, showing a sunlit area of the Central Pacific Ocean and its cloud ...
The James Webb Space Telescope's sightseeing tour just provided a fresh look at one of the most recognizable interstellar objects. Researchers have captured their most detailed image yet of the ...
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. [150]
