To sum it all up, these galaxy bubbles, which seem to be making some type of giant space sandwich out of the Milky Way, likely formed when the supermassive black hole at the center, Sagittarius A*, hurled out energy and hot gas.

Instead of running wild, the black hole pushed material away and created these balloon-like shapes that glow in different types of light – gamma rays and X-rays.

Researchers studied these bubbles by modeling how energy flows through the galaxy, giving them clues about how the outflow grew so large and how it shaped the area around our galactic core.

The results suggest that this wasn’t caused by exploding stars but rather by a focused burst of energy, or jets, from the black hole.
