ScienceEarly galaxies reportedly spread carbon and oxygen just 500 million years after the Big Bang
Phys.org reports that JWST found early galaxies were sending heavy elements into surrounding space, where gas was expected to remain relatively pristine.
TLDR
Phys.org reports that JWST found galaxies were already sending carbon and oxygen into surrounding space just 500 million years after the Big Bang—about 3% of the universe’s current age. The surrounding gas was expected to remain relatively pristine, making the early presence of these heavy elements notable.
