Oxygen Discovered in Most Distant Galaxy | European Southern Observatory

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected oxygen in JADES-GS-z14-0, the most distant galaxy known so far. This is the earliest detection of oxygen yet, and it is very intriguing. How did galaxies evolve fast enough to get enriched with heavy elements like oxygen so early on?

In this Chasing Starlight episode, we will show you everything behind this incredible achievement, and explain how it is changing what we knew about the conditions of the early Universe.
