JWST Finds Early Galaxies Were Already Seeding the Universe with Heavy Elements

JWST finds early galaxies were already seeding the universe with heavy elements

Contrary to conventional wisdom holding that early galaxies were composed of mostly hydrogen and helium, new observations suggest that galaxies were seeding the cosmos with heavy elements just 500 million years after the Big Bang.

Early Galaxies Were Already Enriched In Heavy Elements And Spewing Them Out, Significantly Changing Our Understanding Of The Early Universe

Just 500 million years after the Big Bang, most of the cosmic gas had already been polluted by stars.

JWST finds early galaxies were already spreading the ingredients for planets and life

Story excerpt: Three infant galaxies already contained disturbed, metal-rich gas, showing that cosmic chemical recycling began remarkably early.

Webb Telescope Finds Early Galaxies Were Already Spreading the Ingredients for Planets and Life

Just 500 million years after the Big Bang, the universe was a very different place. The first galaxies had formed, but astronomers expected much of the gas around them to remain almost untouched. It should have contained mostly hydrogen and helium, the two simple elements left over from the universe’s beginning. New observations from NASA’s […]
