Fermi Discovers Giant Gamma-ray Bubbles
Using data from NASA's Fermi Gamma-ray Space Telescope, scientists discovered a gigantic, mysterious structure in our galaxy. This feature looks like a pair of bubbles extending above and below our galaxy's center. Each lobe is 25,000 light-years tall and the whole structure may be only a few million years old.
