Astronomers know how the first quasars formed

Twinkling like cosmic beacons on a shore 13 billion light-years from Earth, quasars are among the oldest and brightest relics of the early Universe that astronomers can discover today.

Short for “quasi-stellar radio sources,” quasars are gigantic black holes that shine as brightly as galaxies and are millions to billions of times more massive Earths sun. Today quasars exist in the centers of many large galaxies. But thanks to their extraordinary luminosity, quasars have been tracked over long distances leisureabout 200 of them have been identified as being within the first billion years of our universe’s history.
