Why is there a hole in the center of this nebula? A leading explanation is that it is caused by the stellar winds from the stars that live there. Stars [ http://antwrp.gsfc.…] - including the Sun [ http://antwrp.gsfc.…] - expel electrons, protons, and other charged ions [ http://www-spof.gsf…] in a steady stream - the stellar wind [ http://www-spof.gsf…]. The wind ions push out the normal hydrogen [ http://antwrp.gsfc.…] and helium [ http://antwrp.gsfc.…] gas found glowing in the nebula.
