GST meaning in Academic & Science ?

The Goode Solar Telescope (GST) is a scientific facility for studies of the Sun named after Philip R. Goode.It was the solar telescope with the world's largest aperture in operation for more than a decade. Located in Big Bear Lake; California, the Goode Solar Telescope is the main telescope of the Big Bear Solar Observatory operated by the New Jersey Institute of Technology (NJIT). Initially named New Solar Telescope (NST), first engineering light was obtained in December 2008, and scientific observations of the Sun began in January 2009. On July 17, 2017, the NST was renamed in honor of Goode, a former, and founding director of NJIT's Center for Solar-Terrestrial Research and the principal investigator of the facility. Goode conceived, raised the funds, and assembled the team that built and commissioned the telescope, and it was the highest resolution solar telescope in the world (until the end of 2019) and the first facility class solar telescope built in the U.S. in a generation.

The GST is capable of observing the Sun in visible to near-infrared wavelengths and features a 1.7-meter primary mirror in an off-axis Gregorian configuration that provides a 1.6-meter clear, unobstructed aperture. Adaptive optics correct for atmospheric schlieren in the solar image known as astronomical seeing.
