Ripples In Space: Gravitational Waves in Our Future

After decades of effort, the era of gravitational wave astronomy is finally here. Ground-based instruments like LIGO have opened up humanity's ears to the ripples of spacetime.

But the LIGO results represent just one slice of the gravitational wave spectrum. There is a lower-frequency rumble in spacetime that requires a space-based instrument to hear.

This Hangout will feature a discussion of LISA Pathfinder, a mission led by the European Space Agency with contributions from several European Member States and NASA, which seeks to demonstrate the technologies needed to build a space-based gravitational wave observatory.

Paul McNamara of ESA and Ira Thorpe of NASA will explain the exciting first results from LISA Pathfinder, which were published and announced on June 7th.
