Astronomers Rule Out Giant Planet in Nearby Binary System After 171-Year Search
Astronomers have closed the book on a long-running claim that a giant planet orbits the nearby binary star system 70 Ophiuchi, ending a search that dates to the 19th century. New analysis suggests earlier signals were not evidence of a planet at all, but the result of stellar activity and observational noise. The finding sharpens the challenge of detecting worlds in complex multi-star systems, where false positives can persist for generations.
