Image of the area in visible light made by the 6.5-metre Magellan Telescope in Chile. Visible in the centre of this image is the light arc around the very massive galaxy in the centre of the newly found distant cluster. The light arc is caused by the gravity field of the galaxy that works as a lens magnifying an object that lies even much farther away, behind the cluster.
