Fermi bubbles are large, lobular regions of gamma-ray emission located above and below the center of the Milky Way galaxy. Discovered by the Fermi Gamma-ray Space Telescope in 2010, these bubbles extend about 25,000 light-years in height and are thought to be a result of interactions between cosmic rays, gas, and magnetic fields in the galaxy.
The origin of the Fermi bubbles is still a topic of research. One leading hypothesis suggests that they
