India's first space observatory ASTROSAT completes two years
Launched on September 28, 2015, ASTROSAT, India's first multi-wavelength space-based observatory has completed two years in Earth's orbit. ASTROSAT has helped scientists confirm the presence of younger stars in globular clusters, earlier believed to contain only old stars. The 1,513-kg satellite has also detected 110 Gamma Ray Bursts, which scientists say, signify the birth of black holes.
