Browsing: LISA

The Laser Interferometer Space Antenna (LISA) is a planned space-based gravitational wave observatory being developed by the European Space Agency (ESA) in partnership with NASA. Scheduled for launch in the 2030s, LISA will consist of three spacecraft arranged in an equilateral triangle, separated by 2.5 million kilometers, forming a massive interferometer in space. This configuration will allow LISA to detect and measure low-frequency gravitational waves from sources like merging supermassive black holes, compact binary systems, and possibly even primordial gravitational waves from the early universe. By observing these cosmic events, LISA aims to complement and expand upon the capabilities of ground-based detectors like LIGO and Virgo, offering insights into fundamental physics, astrophysics, and cosmology.
