Скачать или смотреть JADES GS z14 0: A Galaxy Before Galaxies

Among the most distant objects yet observed, JADES-GS-z-4-0 is a galaxy seen less than 300 million years after the Big Bang (at redshift ~14), and it is heavy: containing about half a billion solar masses in stars. JWST’s MIRI and NIRCam instruments detected strong emission lines and even oxygen which means chemical enrichment (heavier elements) happened very early. What’s stunning is that there seem to have been many luminous, massive galaxies already in place at cosmic dawn, more than some early models had predicted. This one galaxy adds to a growing population that forces us to rethink just how fast structure formed in the early universe.#spacex #astronomy #Astrophysics #cosmology #quantummechanics #jwst #blackholes #nasa
