Space is full of gamma rays and other intense forms of energy, but you've only ever had a partial picture of it. Ground-based telescopes can only see so much, and even the Fermi space telescope (designed to catch these energies) has missed out on a lot of it... until now, that is. NASA has posted a much more complete gamma ray map using 6 years' worth of refined Fermi data. The result is a far more detailed and comprehensive view of the energy 'bright spots' (between 50 billion to 2 trillion electron volts) in the Milky Way galaxy and beyond. The pretty picture you see above includes the leftovers of supernovae, pulsar wind nebulae and even galaxies whose supermassive black holes make them detectable from millions of light years away.
