In 2010, astronomers working with the Fermi Gamma-ray Space Telescope announced the discovery of two giant blobs. These blobs were centered on the core of the Milky Way galaxy, but they extended above and below the plane of our galactic home for over 25,000 light-years. Their origins are still a mystery, but however they got there, they are emitting copious amounts of high-energy radiation.

More recently, the IceCube array in Antarctica has reported 10 super-duper-high-energy neutrinos sourced from the bubbles, leading some astrophysicists to speculate that some crazy subatomic interactions are afoot. The end result: The Fermi Bubbles are even more mysterious than we thought.

Balls - Gas - Starters - Energy - Lot

It's not easy to make big balls of hot gas. For starters, you need energy, and a lot of it. The kind of energy that can spread hot gas to a distance of over 25,000 light-years doesn't come easily to a typical galaxy. However, the peculiar orientation of the Fermi Bubbles — extending evenly above and below our galactic center — is a strong clue that they might be tied our central supermassive black hole, known as Sagittarius A*.

Perhaps millions of years ago, Sag A* (the more common name for our giant black hole, because who wants to keep typing or saying "Sagittarius" all the time?) ate a giant meal and got a bad case of indigestion, with the infalling material heating up, twisting around in a complicated dance of electric and magnetic forces, and managing to escape the clutches of the event horizon before falling in. That material, energized beyond belief, raced away from the center of the galaxy, riding on jets of particles accelerated to nearly the speed of light. As they fled to safety, these particles spread and thinned out, but maintained their energetic state to the present day.
