https://www.youtube.com/watch?v=JqXMxCyWdgoThis composite image shows the ADFS-27 galaxy pair, which is located approximately 12.7 billion light-years from Earth in the direction of the Dorado constellation: the background image is from ESA’s Herschel Space Observatory; the object was then detected by ESO’s Atacama Pathfinder EXperiment telescope (middle image); ALMA (right) was able to identify two galaxies: ADFS-27N (for North) and ADFS-27S (for South). These so-called hyper-luminous starburst galaxies are exceedingly rare at this epoch of cosmic history — near the time when galaxies first formed — and may represent one of the most-extreme examples of violent star formation ever observed.
