COVER The Milky Way seen above the Australian Square Kilometre Array Pathfinder (ASKAP), a radio telescope located in Western Australia. ASKAP's 36 dishes (five visible here) work together as an interferometer to precisely locate radio sources. Astronomers using ASKAP have identified the host galaxy of a fast radio burst, a flash of radio emission lasting only a millisecond. See pages 546 and 565.
