The Music of Gravitational Waves

 

This artist's concept shows the proposed LISA mission, which would consist of three distinct spacecraft, each connected by laser beams. It would be the first space-based mission to attempt the detection of gravitational waves -- ripples in space-time that are emitted by exotic objects such as black holes. (Credit: ESA)

A team of scientists and engineers at NASA’s Jet Propulsion Laboratory has brought the world one step closer to “hearing” gravitational waves — ripples in space and time predicted by Albert Einstein in the early 20th century.The research, performed in a lab at JPL in Pasadena, Calif., tested a system of lasers that would fly aboard the proposed space mission called Laser Interferometer Space Antenna, or LISA. The mission’s goal is to detect the subtle, whisper-like signals of gravitational waves, which have yet to be directly observed. This is no easy task, and many challenges lie ahead.
