But does it create a really good Pepsi belch? Earth surrounded by giant fizzy bubbles

The space above you is fizzing with activity as bubbles of superhot gas constantly grow and pop around Earth, scientists announced Tuesday.

Astronomers found the activity up where Earth's magnetic field meets a constant stream of particles flowing out from the sun.

While space is commonly called a vacuum, in fact there is gas everywhere, albeit not as dense as the air you breathe.
