Dust to Dust

SN1987AGalaxies can be remarkably dusty places, and supernovae are thought to be a primary source of that dust. However, astronomers have had little actual evidence of a supernova’s dust‐making capabilities, and they could not account for the copious amount of dust detected in young, distant galaxies. New observations by the ESO’s Atacama Large Millimeter/submillimeter Array have captured the remains of a recent supernova (SN1987A) 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.
