A Giant Cosmic Observatory in the Making
The European Space Agency (ESA) has officially approved the construction phase for the Laser Interferometer Space Antenna (LISA). Slated for launch in the early 2030s, LISA will be the first space-based gravitational wave detector, consisting of three spacecraft flying in a giant triangular formation millions of kilometers apart.
Listening to Black Hole Mergers
By firing precise laser beams across millions of kilometers of empty space, LISA will detect minuscule ripples in spacetime caused by the violent mergers of supermassive black holes in distant galaxies. This will allow physicists to peer back into the very dawn of the universe, uncovering cosmic phenomena invisible to optical or radio telescopes.
Unmatched Sensitivity Free from Earth Noise
Unlike ground-based detectors like LIGO, a space-based observatory is completely free from seismic noise and environmental vibrations. This allows it to capture low-frequency gravitational waves, opening a completely new sensory window into standard astrophysics and fundamental cosmic laws.
