Meet LISA: The $1.6 Billion Space Telescope That Will Redefine Astronomy


The $1.6 billion mission is an extremely complicated engineering challenge and will make gravitational wave detections in space.

An ambitious, unprecedented space telescope, set to launch next decade, will continue in this tradition, but it will do so in ways never before imagined, with the ability to detect phenomena like gravitational waves—ripples in spacetime that offer a new window into the universe’s most mysterious events. In 2016, the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo collaborations announced the first detections of the subtle waves, which stretch and squeeze the fabric of the universe as they emanate from their ginormous sources. Gravitational waves offer up plenty of information about the systems that generate them, helping scientists revise their catalogues of the possible sizes, environments, and mechanics of black holes and neutron stars.
