11 Fascinating Facts About Our Milky Way Galaxy.
10- There are mysterious bubbles arising out of the Milky Way.
Imagine discovering that your living room, which you've seen a million times before, contained a previously unnoticed elephant. That's more or less what happened to scientists in 2010 when they uncovered gigantic, never-before-seen structures stretching for 25,000 light-years above and below the galaxy. Named 'Fermi bubbles' after the telescope that found them, these gamma-ray-emitting objects have defied astronomers' explanations ever since. Last year, a team gathered evidence suggesting that the bubbles are the aftermath of an energetic event 6 million to 9 million years ago, when the supermassive black hole in the galactic center swallowed a huge clump of gas and dust and burped out the giant, glowing clouds, according to NASA.https://www.livescience.com/63847-facts-about-the-milky-way.html
