Hunting for the neighborhoods of enigmatic fast radio bursts (FRBs), astronomers using the Hubble Space Telescope tracked four of them to the spiral arms of the four distant galaxies shown in the image. The bursts are catalogued as FRB 190714 (top left), FRB 191001 (top right), FRB 180924 (bottom left), and FRB 190608 (bottom right). Because these radio pulses disappear in much less than the blink of an eye, researchers have had a hard time tracking down where they come from. With the help of Hubble's sharp vision, astronomers pinpointed their locations (denoted by the dotted oval lines) to the galaxies' spiral arms.
