• Ultra-high-energy gamma rays detected from Milky Way’s center reveal extreme cosmic energy

    A recent study of High-Altitude Water Cherenkov (HAWC) observatory data showed a violent mystery in the Milky Way galaxy. Pat Harding, a physicist at Los Alamos and the Department of Energy’s principal investigator for the project said that the results are a glimpse at the center of the Milky Way to an order of magnitude higher energies than ever seen before.

  • Gamma rays will reach beyond the limits of light

    Researchers have discovered a new way to produce high energy photon beams. The new method makes it possible to produce these gamma rays in a highly efficient way, compared with today's technique. The obtained energy is a billion times higher than the energy of…

    Scientists using the Fermi Large Area Telescope have come up empty handed in their quest to prove their theories about dark matter.Tom Wilson explores why institutional science remains determined in its pursuit to prove dark matter's existence.Video courtesy of The

  • Giant “light bulbs” in space?

    For more than four years, NASA scientists has puzzled over mysterious structures in the Milky Way galaxy called Fermi Bubbles. The so-called bubbles reach for tens of thousands of light years above and below the galaxy.Both the structures enormous size and their emissio

  • Sensing lightning from ISS

    Across the atmosphere of Earth, lightning flashes about 50 times per second. That’s 4.3 million times a day and roughly 1.5 billion times a year. Using a new instrument on the International Space Station (ISS), scientists are trying to observe and dissect at

  • Colliding neutron stars source of all the gold in universe

    Contrary to what most people think, it appears that gold did not form inside our planet eons ago. The reason for this conclusion is simple. Gold is heavy, and have it formed before Earth's crust solidified it would have sunk through the liquid

  • Earth Gamma-Ray Blasters

    From NASA Goddard Space Flight Center. NASA’s The Fermi Gamma-ray Space Telescope has been catching brief outbursts of high-energy light that are mysteriously produced above thunderstorms. The outbursts, known as terrestrial gamma-ray flashes (TGFs), last only a few
