Giant Bubble Bullies Our Space

"When stars explode as supernova, they carve giant bubbles in space. Our own solar system is enveloped by such a structure from a long-ago explosion.

Now scientists have shown that our bubble is being pinched and bullied backward by another expanding bubble forged from multiple supernovas.

Our bubble is called the Local Bubble by astronomers. It’s shaped like an hourglass. The bully goes by the name of Loop 1 Superbubble; it’s the result of several exploded stars over the past few million years, researchers figure.

Superbubble’s outer boundaries are marked by hot, expanding gas that radiates low-energy X-rays."
