|Star-birth stage observed for the first time|
Astronomers perhaps feel some of the same sort of excitement in observing the stages of star formation as fathers do in witnessing the birth of their children. For the last two decades astronomers have repeatedly enjoyed watching the various stages and aspects of star birth-except for one that has eluded their view: the core region of a very early stage. When a gas cloud collapses into a star, only the innermost regions actually shrink. This is because the shrinking takes place so fast that it triggers a powerful wind that blows away the outer layers of the gas cloud. This blowing away has now been viewed many times by many astronomers. But the shrinking component was hidden from view because no tool existed for looking through the outer layers down into the core.
