    From the intricate brightening pattern of this source, the astronomers realised that the celestial body acting as a 'cosmic magnifying lens' was a binary system: a pair of rather small stars, orbiting each other in less than three years 🌟💫💫🔭 Details 👉

    This unusual behaviour was caused by gravitational – an effect predicted by Einstein’s theory of general relativity, as the of massive objects (eg. a star) bends the fabric of spacetime in their vicinity & distorts the path of light from background sources
