Million-Degree Plasma May Flow throughout the Galaxy

Researcher Manuel Güdel at the Paul Scherrer Institut in Switzerland and colleagues from Switzerland, France and the US have recently observed the plasma flow phenomenon for the first time in the Orion Nebula. Based on images taken with an x-ray satellite called the XMM-Newton, the researchers observed the existence of a million-degree plasma flowing from the nebula into the adjacent interstellar medium, and then into the neighboring superbubble Eridanus.

“Although there has been a theoretical model that predicted hot gas bubbles blown by just one massive star, such has not been detected until we found confirmation in the Orion Nebula,” Güdel told “We didn’t look for it – we actually found this diffuse emission by chance while looking at the many stellar x-ray point sources in the field.

“Hot gas has been seen in some extremely massive star-formation regions, and some of this gas might have been produced by supernova explosions,” said Güdel. “However, the Orion Nebula is the first region of its (more modest) kind that shows this phenomenon, and there is no supernova that can account for it. Such more modest regions of star formation are naturally more frequent in the galaxy than the more extreme cases. Therefore, we believe that plasma outflows from star-forming regions are widespread.”
