Fermi Bubbles

The Fermi Bubbles, which were originally noticed in 2010, are located right at the core of the Milky Way galaxy. A Fermi Bubble: What Is It? There are two of them in our galaxy. It's a huge glob. They form a big figure eight with one above and one below, sort of straddling the galaxy's midsection. They are around 25,000 light years away from the galactic plane. Thus, they are large blobs.

The intense plasma that makes up the Bubbles causes them to produce a lot of gamma and x-ray energy. Due to their peculiarity and rarity, little much is known about them other than the fact that their structure and location imply some connection to the galaxy's black hole. There are high energy neutrinos in them, and they appear to be energetic plasma structures connecting the blobs at the top and bottom.

There are a number of suggestions as to what might have generated the bubbles, all of which are now simply wild conjecture. These possibilities range from a star going into the black hole to multiple stars, numerous stars, several, simultaneous supernovas, and a few others.
