Astronomers trace repeating space signals to star pair (opens in new tab)

Astronomers reported that a repeating source of radio bursts, ASKAP J1745, comes from a pair of stars orbiting each other, giving researchers an identified source for a class of unexplained signals called long-period transients. The study, published in Nature Astronomy, detected radio and X-ray bursts that repeated with each orbit of the system. Astronomers first found long-period transients in wide-area sky surveys. About a dozen such sources are known, and most remain unexplained. The Phys....
