The distant dusty galaxy A1689-zD1 behind the galaxy cluster Abell 1689

This spectacular view from the NASA/ESA Hubble Space Telescope shows 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 in this picture òÀÔ although it is still so faint that it is barely seen.

New observations with ALMA and ESOòÀÙs VLT have revealed that A1689-zD1ˆàis a dusty galaxy seen when the Universe was just 700 million years old.
