NASA reveals prototype for LISA telescopes to detect gravitational waves in space
Summary: NASA has introduced the prototype for six telescopes that will be part of the Laser Interferometer Space Antenna (LISA) mission. This mission, led by the European Space Agency, aims to be the first gravitational wave detector in space, set to launch around 2035.
LISA will consist of three spacecraft in a triangular formation, about 50 million kilometers from Earth. Each spacecraft will have two telescopes that use lasers to detect gravitational waves, which are ripples in spacetime caused by massive cosmic events.
The prototype, made from a special glass-ceramic, is designed to withstand temperature changes and enhance infrared laser reflection. Studying gravitational waves will help scientists explore phenomena that are invisible to traditional astronomy, such as black holes and the early universe.
