Journey to The Most Distant Galaxy to Date JADES-GS-z14-0: Oxygen Detected | ESO

This video zooms into the galaxy JADES-GS-z14-0, the most distant galaxy confirmed to date. Thanks to the Atacama Large Millimeter/submillimeter Array (ALMA), a telescope operated by the European Southern Observatory and its international partners, astronomers have now uncovered the presence of a surprising element after examining its light spectrum: oxygen. The presence of heavy elements like oxygen suggests that the formation of these early galaxies happened much faster than we thought. It must have had multiple generations of stars being born and dying. 

The various images shown here, blended together to create this zoom, come from telescopes at distinct time intervals, ending with close-up of the galaxy as seen by ALMA, together with the spectrum recovered by two independent research teams.
