In first, scientists detect light from gravitational wave source

By Scott Malone CAMBRIDGE, Mass. (Reuters) - Scientists in the United States and Europe have for the first time detected gravitational waves, the ripples in space and time predicted by Albert Einstein, at the same time as light from the same cosmic event, according to research published on Monday. The waves, caused by the collision of two neutron stars some 130 million years ago, were first detected in August by the Laser Interferometer Gravitational-Wave Observatories, known as LIGO, in Washington state and Louisiana as well as at a third detector, named Virgo, in Italy. Two seconds later, observatories across earth and in space detected a burst of light in the form of gamma rays from the same part of the southern sky, which analysis showed was likely to be from the same source.
