Infrared/visible-light view of the distant dusty galaxy A1689-zD1 behind the galaxy cluster Abell 1689

This view includes infrared light images from the WFC3 instrument on the NASA/ESA Hubble Space Telescope as well as visible light views. It shows a close up look at part of the rich galaxy cluster Abell 1689. The huge concentration of mass bends light coming from more distant objects and can increase their total apparent brightness and make them visible. One such object, A1689-zD1, appears on this picture as the elongated reddish object in the box.

New observations with ALMA and ESO’s VLT have revealed that A1689-zD1 is a dusty galaxy seen when the Universe was just 700 million years old. Its light has been magnified by a factor of more than nine by the massive gravitational lensing effect of the cluster.
