The Antarctica Schmidt Telescopes project (also known as Antarctic Survey Telescopes (AST3)) is a joint project between Texas A&M University (TAMU) and the Beijing Astronomical Observatory to build three small (50cm aperture) wide-field telescopes at the Antarctic Kunlun Station near Dome A in Antarctica; Lifan Wang at TAMU is the main instigator of the project.
Telescope domes have a slit or other opening in the roof that can be opened during observing, and closed when the telescope is not in use. In most cases, the entire upper portion of the telescope dome can be rotated to allow the instrument to observe different sections of the night sky. Radio telescopes usually do not have domes.

The observatory's main dome houses a 40 in-diameter (102 cm) doublet lens refracting telescope, the second-largest refractor ever successfully used for astronomy. The largest lens is the Swedish 1-m Solar Telescope. There are several smaller telescopes – some permanently mounted – that are primarily used for educational purposes.
YouTube Kids has faced criticism from advocacy groups, particularly the Fairplay Organization, for concerns surrounding the app's use of commercial advertising, as well as algorithmic suggestions of videos that may be inappropriate for the app's target audience, as the app has been associated with a controversy surrounding disturbing or violent ...
The 1.54-metre Danish National Telescope was built by Grubb Parsons and has been in use at La Silla since 1979. The telescope has an off-axis mount, and the optics are a Ritchey-Chrétien design. The telescope's mount and the limited space inside the dome induce significant pointing restrictions. [32]
Software packages such as BSMEM or MIRA are used to convert the measured visibility amplitudes and closure phases into astronomical images. The same techniques have now been applied at a number of other astronomical telescope arrays, including the Navy Precision Optical Interferometer, the Infrared Spatial Interferometer and the IOTA array.
Common completed this telescope by 1879, and went on to make a 60-inch telescope; he sold the 36-inch to Crossley. [1] Crossley set the telescope up in Halifax, England in a new dome. [1] Meanwhile, at the Lick Observatory in California, Edward S. Holden, the director, learned that Crossley wanted to sell the well-regarded Common 36-inch ...
The Kunlun Dark Universe Survey Telescope, also known as KDUST, [1] is a planned large survey telescope to be installed at the Chinese Antarctic Kunlun Station [2] located at Dome A ice plateau in Antarctica. It is intended to take advantage of the exceptional observation conditions due to low temperature, clean air quality and low disturbances ...
