LISA

LISA stands for “Laser Interferometer Space Antenna.” It is a planned space mission by the European Space Agency (ESA) aimed at detecting and studying gravitational waves. These waves are ripples in spacetime caused by some of the most violent and energetic processes in the universe, such as merging black holes and neutron stars. LISA will consist of three spacecraft arranged in a triangular formation, which will be positioned millions of kilometers apart in space. By measuring the tiny changes in distance between these spacecraft caused by passing gravitational waves, LISA aims to provide profound insights into astrophysics, cosmology, and the fundamental nature of gravity. The mission is expected to contribute significantly to our understanding of the universe and the dynamics of massive astronomical objects.
