New Revolutionary Theory of Dark Matter

  The Universe abounds with dark matter. Nobody knows what it consists of. Physicists from the University of Oslo have now launched a very hard mathematical explanation that could solve the mystery once and for all. SIGNS OF DARK MATTER: The image shows all the gamma rays recorded by the Fermi-LAT space probe as a map [continue reading]

"Cosmic fog" of the Nearby Universe measured

  Researchers from the Laboratoire Leprince-Ringuet (CNRS/École Polytechnique) have carried out the first measurement of the intensity of the diffuse extragalactic background light (EBL) in the nearby Universe, a fog of photons that has filled the Universe ever since its formation. Using some of the brightest gamma-ray sources in the southern hemisphere, the study was [continue reading]

Fermi Measures Cosmic 'Fog' Produced by Ancient Starlight

  Astronomers using data from NASA’s Fermi Gamma-ray Space Telescope have made the most accurate measurement of starlight in the Universe and used it to establish the total amount of light from all of the stars that have ever shone, accomplishing a primary mission goal. This plot shows the locations of 150 blazars (green dots) [continue reading]

Blazars Still Mysterious Cosmic Objects

  A blazar is a galaxy with an intensely bright central nucleus containing a supermassive black hole, much like a quasar. The difference is that a blazar can emit light with extremely high energy gamma rays that are sometimes over a hundred million times more energetic than the highest energy X-rays that the Chandra X-ray [continue reading]

Evidence of Dark Matter Found?

  Gamma-ray photons seen emanating from the center of the Milky Way galaxy are consistent with the intriguing possibility that dark-matter particles are annihilating each other in space, according to research submitted by UC Irvine astrophysicists to the American Physical Society journal Physical Review D. 360-degree panorama view of the Milky Way Galaxy (an assembled [continue reading]
