Superbubble
Okay kiddo, so you know how when you blow bubbles with gum or soap, they get bigger and bigger until they pop? Well, imagine if there was a bubble in space that was really, REALLY big - like bigger than our whole solar system! That's called a superbubble.
Superbubbles are created when a bunch of stars are formed in the same spot. When stars are born, they give off a lot of heat and light, but they also create powerful winds that blow gas and dust away. When lots of stars are doing this together, their winds combine and can push gas and dust really far out into space.
But there's more! Sometimes these stars can also go out with a bang, in something called a supernova. When a star explodes like this, it sends out a shockwave that can push even more gas and dust away. So when lots of stars in the same area are exploding, the shockwaves from all those explosions can combine and create a gigantic bubble.
These superbubbles can be really important in space, because they help shape and change the environment around them. They can push gas and dust around, which can trigger the birth of new stars in different places. Plus they're really pretty to look at! Scientists use special telescopes to study superbubbles and learn more about how they work.
