Q. What is the main objective of Astrosat mission, recently seen in the news?
Answer:
To study celestial sources in the X-ray, optical & spectral bands simultaneously
Notes: Indian astrophysicists used AstroSat to discover aperiodic modulation of high-energy X-rays in Swift J1727.8-1613, a black hole binary source. AstroSat, India's first dedicated astronomy mission, launched in 2015, observes celestial sources in X-ray, optical, and UV bands simultaneously. It carries five scientific payloads for imaging and studying cosmic sources. Unique for enabling multi-wavelength observations, AstroSat is controlled from Bengaluru. Its objectives include studying binary systems, star birth regions, and conducting deep-field surveys.
