WISE J1517+05 flashes powerful radio bursts every 1.149 hours, making it one of the fastest-spinning ultracool dwarfs detected in radio waves. The latest reports also explore how transit changes can reveal a hidden planet in Kepler-88 and map a possible hotspot on WD 1202-024 B. Other findings track helium in V1298 Tau b’s atmosphere and a warped dust ring around CQ Tau.
