Jupiter size refined by new radio mapping

Paris, France (SPX) Feb 04, 2026

For more than half a century, planetary scientists relied on a handful of spacecraft flybys to pin down Jupiter’s size and shape. Now, an international team led by the Weizmann Institute of Science has used a trove of new radio data from NASA’s Juno mission to redraw the gas giant with unprecedented precision.

The study, published in Nature Astronomy, replaces six measurements from NASA’s
