Astronomers identify binary source of repeating cosmic signals (opens in new tab)

An international team led by University of Sydney astronomers said it had found the clearest evidence yet for the source of a rare class of repeating cosmic signals known as long-period radio transients, using CSIRO's ASKAP radio telescope in Western Australia. The object, ASKAP J1745-5051, appears to be a binary system containing a white dwarf and a companion star that produces repeating radio bursts, according to accounts of the study published June 1. Researchers described ASKAP J1745 as a...
