A gravitational lens system has been discovered by undergraduate students examining images from the 8.2-metre Subaru Telescope’s Hyper Suprime-Cam. Dubbed the “Eye of Horus” due to the system’s uncanny resemblance to the sacred eye of the ancient Egyptian goddess, it is formed by a galaxy 7 billion light-years from the Earth bending the light from two more galaxies directly behind it.
