NASA's Fermi Telescope Finds Giant Structure in our Galaxy

January 10, 2013
The bubbles display a spectrum with higher peak energies than the diffuse gamma-ray glow seen throughout the sky. In addition, the bubbles display sharp edges in Fermi LAT data. Both of these qualities suggest that the structure arose in a sudden, impulsive event. Credit: NASA/DOE/Fermi LAT/D. Finkbeiner et al.
