| Mystery of planet-forming disks explained by magnetism Posted: 07 Mar 2014 09:46 AM PST Astronomers say that magnetic storms in the gas orbiting young stars may explain a mystery that has persisted since before 2006. Researchers using NASA's Spitzer Space Telescope to study developing stars have had a hard time figuring out why the stars give off more infrared light than expected.
