ADFS-27 Galaxy Pair (IMAGE) National Radio Astronomy Observatory Caption Composite image of ADFS-27 galaxy pair. The background image is from ESA's Herschel Space Observatory. The object was then detected by ESO's Atacama Pathfinder EXperiment (APEX) telescope (middle image). ALMA (right) was able to identify two galaxies: ADFS-27N (for North) and ADFS-27S (for South). The starbursting galaxies are about 12.8 billion light-years from Earth and destined to merge into a single, massive galaxy. Credit NRAO/AUI/NSF, B.
