The Next Orion Nebula

Summary - (Jan 11, 2006) The Orion Nebula is one of the most magnificent objects in the night sky, but it won't last forever. Fortunately, astronomers now think they know where its successor will show up. A glowing gas cloud in the constellation Cassiopeia called W3 has just begun to shine with newborn stars. In just 100,000 years, it should be blazing in the night sky; just as the Orion Nebula fades from view. W3 was recently found to have a collection of massive protostars packed tightly together, eating away at a surrounding cocoon of gas and dust that obscures them from view.
