Using gravitational lensing, a team of scientists from the Instituto de Astrofisica de Canarias (IAC) has discovered a very distant galaxy, some 10 thousand million light years away, about a thousand times brighter than the Milky Way. It is the brightest of the submillimetre galaxies, called this because of their very strong emissionin the far infrared. To measure it they used the Gran Telescopio Canarias (GTC) at the Roque de los Muchachos Observatory (GarafÃa, La Palma).
