Indian satellite helped in 3rd gravitational wave detection
India's first space observatory ASTROSAT, launched by ISRO in 2015 helped confirm the third detection of gravitational waves by the Laser Interferometer Gravitational-wave Observatory (LIGO), announced on June 1. Indian scientists at LIGO used the satellite to rule out X-rays accompanying the waves created by merging of two black holes, consistent with Albert Einstein's prediction 100 years ago.
