Astronomers have finally tracked down missing "ordinary" matter, which they discovered hiding as gas spread out in the vast expanses between galaxies.

Of the 69 FRBs used by the team, 39 were discovered by a network of 110 radio telescopes located at Caltech's Owen Valley Radio Observatory (OVRO) called the Deep Synoptic Array (DSA). The DSA was built with the specific mission of spotting and localizing FRBs to their home galaxies.

Bright flashes of enigmatic radio waves have helped illuminate some of the missing matter in the universe, astronomers say in a new study.
