Very distant, active supermassive black holes are the brightest beacons in the universe. Known as quasars, these behemoths are surrounded by equally distant galaxies. In recent decades, researchers have gone on a cosmic treasure hunt and identified the three most distant quasars known over the last three years—each more than 13 billion light-years from Earth. Astronomers theorize that it can take billions of years for supermassive black holes and their accompanying galaxies to form. How is it possible that these quasars became so gigantic, with billions of solar masses, in the first 700 million years of the universe? Once you can see past their glare, what do their accompanying galaxies look like? And what do their "neighborhoods" look like?
