70 telescopes confirmed light tied with gravitational waves
Over 70 space and ground-based observatories have confirmed the light emission accompanied with the fifth gravitational wave detection, made by LIGO/VIRGO detectors on two continents. The high-energy gamma-ray bursts were first observed by NASA's Fermi Gamma-ray Space Telescope and the Hubble Space Telescope. Ground-based telescopes in India, Chile, and Australia also helped confirm the detection.
