For a bubble this size, this is very close. |
One theoretical model shows that young stars could power an outflow that matches what we see very closely. |
This giant gas bubble contains about a million times more mass than the Sun and the energy powering its outflow is equal to about 100 supernova explosions. |

This is a huge number. |
This would shut down the formation of new stars in the galaxy. |
We see that all the hydrogen gas in this region of the Galaxy is disturbed, with many smaller outflows closer to the plane of the Galaxy and then a giant plume of gas that forms a sort of cap on the whole thing. |
