A1689-zD1 as seen by ALMA

A1689-zD1 is a star-forming galaxy located in the Virgo constellation cluster. It was first observed thanks to gravitational lensing from the Abell 1689 galaxy, which made the young galaxy appear nine times more luminous. New observations made using the Atacama Large Millimeter/submillimeter Array (ALMA) are revealing to scientists that the young galaxy, and others like it, may be bigger and more complex than originally thought.
