UVIT

UVIT, or the Ultra Violet Imaging Telescope, is a space-based observatory designed to study celestial objects in the ultraviolet (UV) spectrum. It is a part of the AstroSat mission, India's first dedicated multi-wavelength space observatory. Launched in 2015, UVIT is a collaboration between the Indian Space Research Organisation (ISRO) and various international partners.

UVIT is equipped with two co-aligned telescopes, each with a 38 cm diameter aperture, providing a wide field of view of 28 arcminutes. It operates in three UV bands: near-UV (NUV), far-UV (FUV), and visible light. The NUV band covers wavelengths from 200 to 300 nanometers, while the FUV band covers wavelengths from 130 to 200 nanometers. The visible light band covers wavelengths from 320 to 550 nanometers.

The primary scientific objectives of UVIT include studying the evolution of stars, the nature of galaxies, and the distribution of interstellar matter. It has contributed to various astronomical discoveries, such as the detection of UV emissions from distant galaxies and the study of stellar winds in massive stars.

UVIT's unique capabilities have made it a valuable tool for astronomers worldwide, providing insights into the UV properties of celestial objects that are not accessible from the ground due to Earth's atmosphere. Its data has been used in conjunction with observations from other telescopes to enhance our understanding of the universe.
