LISA Pathfinder success paves way for space-based gravitational wave detection

9 June 2016 Astronomy Now

LISA Pathfinder, a mission led by the European Space Agency with contributions from NASA, has successfully tested key technology needed to build a space-based observatory for detecting gravitational waves. These tiny ripples in the fabric of space, predicted by Albert Einstein a century ago, were first seen last year by the ground-based Laser Interferometer Gravitational-Wave Observatory (LIGO).
