Astronomers have traced the signal of an enigmatic repeating fast radio burst for only the second time -- and it's in a spiral galaxy similar to our own, not so far away.
Fast radio bursts, or FRBs, are millisecond-long bursts of radio waves in space. Individual radio bursts emit once and don't repeat. Repeating fast radio bursts are known to send out short energetic radio waves multiple times.
Striking new observations with the Atacama Large Millimeter/ submillimeter Array (ALMA) telescope capture, for the first time, the remains of a recent supernova brimming with freshly formed dust. If enough of this dust makes the perilous transition into interstellar space, it could explain how many galaxies acquired their dusty, dusky appearance.
