NASA’s Fermi Gamma-ray Space Telescope has unveiled a previously unseen structure at 90 degrees to the plane in the Milky Way. The feature spans 50,000 light-years . Previous satellites had shown hints in the x-ray part of the spectra, but scientist discovered the new structures while processing the whole sky data.

These structures extend 25,000 light years above and below the plane of the galaxy, possible expalnatiion may be high energy electrons that were emmited in the past by the supermassive black hole in the galactic core. A video below shows a little more detail on this.
