AstroSat

AstroSat is India's first dedicated multi-wavelength observatory satellite. Launched by the Indian Space Research Organisation (ISRO) on September 28, 2015, its primary mission is to observe celestial objects across a wide range of ultraviolet and X-ray wavelengths. This unique capability allows astronomers to study cosmic phenomena in unprecedented detail.

The satellite carries four scientific instruments: the Ultraviolet Imaging Telescope (UVIT), the Large Area X-ray Proportional Counter (LAXPC), the Soft X-ray Imaging Spectrometer (SAXSI), and the Cadmium Zinc Telluride Imager (CZTI). UVIT is designed to study the sky in ultraviolet and visible light, providing imaging and spectroscopic capabilities. LAXPC and SAXSI are X-ray instruments that detect and measure X-rays from celestial sources, while CZTI offers imaging of hard X-rays.

AstroSat’s orbit is a low Earth orbit, allowing for relatively stable observations. Its scientific objectives include studying star formation regions, understanding stellar evolution, investigating active galactic nuclei and black holes, and exploring the nature of dark matter and dark energy. The data collected by AstroSat is made available to the global scientific community, fostering international collaboration in astrophysics research. The satellite has already contributed significantly to our understanding of various cosmic phenomena, including supernovae, neutron stars, and distant galaxies.
