Indian Express: Gravitational-wave enthusiasts have another reason to celebrate. India's Union Cabinet has given what it calls in-principle approval to build a gravitational-wave observatory in the country. The announcement comes less than a week after scientists with the Laser Interferometer Gravitational-Wave Observatory (LIGO) reported the first-ever direct detection of gravitational radiation. An observatory in India would give LIGO a third detector (the others are in Louisiana and Washington State) to detect gravitational waves and triangulate the position of sources in the sky. Italy's Virgo, Germany's GEO600, and the KAGRA detector under construction in Japan would join LIGO's detector trio in a global network.
