One of the strangest cosmic phenomena ever observed in the Milky Way galaxy is the Fermi Bubbles. In 2010, astronomers using the Fermi Gamma-ray Space Telescope discovered the so-called bubbles — giant structures, mostly composed of gamma-rays, that stretch for tens of thousands of lightyears above and below the Milky Way’s spiral disk.
The so-called bubbles’ incredible size and weird energetic emissions have been a source of ongoing puzzlement for the last decade. However, plasma physicists can easily see the bubbles as demonstrations of electrical phenomenon documented in laboratories over many decades.
