Superbubbles in the LMC
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 - including the Sun - expel electrons, protons, and other charged ions in a steady stream - the stellar wind . The wind ions push out the normal hydrogen and helium gas found glowing in the nebula. This star forming region is located in the Large Magellanic Cloud . This picture is a composite of three separate photographs, each sensitive to only one specific color of light - a color that distinguishes a specific chemical element . It is currently not known why stars emit a stellar wind.
