NASA has revealed the first look at a full-scale prototype for six telescopes that will enable, in the next decade, the space-based detection of gravitational waves — ripples in space-time caused by merging black holes and other cosmic sources. The LISA (Laser Interferometer Space Antenna) mission is led by ESA (European Space Agency) in partnership […]
Telescope is almost a misnomer here. It will be “looking” at other satellites, not astronomically distant objects.
The influence of gravitational waves will be seen in changes in the relative distance to each of the six satellites.
