Bedtime Astronomy

Using the Atacama Large Millimeter/submillimeter Array, astronomers confirmed a rare pair of quasars inside merging galaxies from the early universe.

A tidal bridge of ionized carbon reveals they are a true binary system—not an illusion caused by gravitational lensing. Formed less than a billion years after the Big Bang, these galaxies host two growing supermassive black holes destined to collide. 

The eventual merger will generate powerful gravitational waves, offering insight into how galaxy interactions shape cosmic evolution.
