Using the sun as a baseline, astronomers can measure when a #star formed by determining its #metallicity, or the level of heavy elements present within it. Metal-rich #stars or nebulas formed relatively recently, while metal-poor objects we

What “metallicity” means
Wiktionary · WikipediaIn astronomy, metallicity is the abundance of elements present in an object that are heavier than hydrogen and helium. Most of the normal currently detectable matter in the universe is either hydrogen or helium, and astronomers use the word metals as convenient shorthand for all elements except hydrogen and helium. This word-use is distinct from the conventional chemical or physical definition of a metal as an electrically conducting element. Stars and nebulae with relatively high abundances of
