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.

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...

One theoretical model shows that young stars could power an outflow that matches what we see very closely.

This is a huge number.

For a bubble this size, this is very close.

This would shut down the formation of new stars in the galaxy.
