James Webb Space Telescope plans probe of massive star radiation
The James Webb Space Telescope will zero in on a portion of the famous Orion Nebula, the closest region of mass star-formation to Earth, to learn more about how massive young stars shape their environments. The Orion Nebula, some 1,350 light-years away from Earth, is known as a stellar nursery. Dense clouds of gas and dust in this region collapse into stellar embryos that gradually grow bigger until the pressure and heat in their cores increases enough to trigger nuclear fusion.
