In 2010, observations carried out by the Fermi Gamma Ray Telescope revealed two enormous structures associated with our Milky Way galaxy. These two lobe-like structures have been dubbed Fermi Bubbles, and they span about 50000 light-years. Their origin is not entirely known, but they maybe related to superheated gas emitted by Sgr A*, the supermassive black hole at our galaxy's centre | |
