Hundreds of Ancient Quasars Found in the Distant Universe
In a groundbreaking discovery, astronomers have recently found hundreds of new high-redshift quasars, some of which were formed when the universe was just 800 million years old. Quasars are incredibly bright objects that are powered by supermassive black holes, which feed on gas and dust and create a brilliant light that can be seen from far away galaxies.
The new quasars were identified by combining data from the Sloan Digital Sky Survey and the Wide-field Infrared Survey Explorer, and then further analyzing the data with a machine learning algorithm. This new discovery will help scientists gain a better understanding of the early universe and the formation of galaxies.
