The evolved Laser Interferometer Space Antenna (eLISA) is a European Space Agency observatory concept designed to detect gravitational waves from space. It consists of three spacecraft flying in a triangular formation millions of kilometers apart, using precise lasers to measure minute changes in distance caused by passing gravitational waves. Placing the interferometer in space avoids seismic noise that limits ground-based detectors.
