The European Space Agency (Esa) has given the green light for the first mission to detect and study gravitational waves from space.

Designed to detect the ripples caused by the collision of supermassive black holes, the Lisa (Laser Interferometer-Space Antenna) mission is the most expensive and complex Esa mission to-date.
