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.
The planet-forming disks that circle the young stars are heated by starlight and glow with infrared light, but Spitzer detected additional infrared light coming from an unknown source.
A new theory, based on the three-dimensional model of planet-forming disks, suggests an answer: Gas and dust disks suspended above the giant magnetic loops as the sun absorb starlight and glow with infrared light.
