Quasars are among the brightest, most energetic objects in the universe, powered by supermassive black holes devouring matter at the centers of galaxies. Their extreme luminosity makes them visible across tremendous cosmic distances.

Think of quasars as time machines. Rare but revealing. They are light from the beginnings of the universe that let astronomers investigate how early galaxies formed.

Los hallazgos representan un avance significativo en la comprensión del universo primitivo.
