NASA's Webb to study how massive stars' blasts of radiation influence their environments

In a nearby stellar nursery called the Orion Nebula, young, massive stars are blasting far-ultraviolet light at the cloud of dust and gas from which they were born. This intense flood of radiation is violently disrupting the cloud by breaking apart molecules, ionizing atoms and molecules by stripping their electrons, and heating the gas and dust. An international team using NASA's James Webb Space Telescope, which is scheduled to launch in October, will study a portion of the radiated cloud call...
