A very energetic star in the center of the bubble of gas is classified as being "Wolf-Rayet" type and is very rare. These stars are incredibly hot (25,000-50,000K) and expell their outer layers of gas at tremendous velocities (thousands of kilometers per second). This particular star lives in an area of the galaxy (at least 10000 light years away) that contains clouds of interstellar gas.

Distance: 10,000 light years.
