Planck and Fermi combined all-sky images. This image shows the distribution of the Milky Way's galactic haze (red and yellow) seen by ESA's Planck mission at microwave frequencies superimposed over the high-energy sky (blue), as seen by NASA's Fermi Gamma-ray Space Telescope (FGST). The Planck data is at frequencies of 30 and 44 GHz. The Fermi data corresponds to observations performed at energies between 10 and 100 gigaelectronvolts. It shows two bubble-shaped, gamma-ray emitting structures extending from the galactic centre. The Planck data for the galactic centre shows synchrotron emission from charged particles. Possible sources for this are enhanced supernova rates, galactic winds and the annihilation of dark matter particles. Image published in 2012. | |
