NASA's newest telescope can detect gravitational waves from colliding black holes

NASA showed off a telescope prototyp e for a new gravitational wave detection mission in space. The telescope is part of the Laser Interferometer Space Antenna (LISA) mission led by the European Space Agency (NSA) in partnership with NASA. The goal of the LISA mission is to position three spacecraft in a triangular orbit measuring nearly 1.6 million miles on each side. The three spacecraft will follow the Earth's orbit around the Sun. Each spacecraft will carry two telescopes to track their sibl...
