An illustration showing the distribution of the two dozen known dwarf satellite galaxies around the Milky Way. Astronomers have recently discovered nine more additional such candidate objects below the plane of the galaxy, shown here in red. Image Credit: S. Koposov, V. Belokurov (IoA, Cambridge). Background: 2MASS The mystery of dark matter has […] New research merging Fermi data with information from ground-based radar and lightning networks shows that terrestrial gamma-ray flashes arise from an unexpected diversity of storms and may be more common than currently thought. Image Credit: NASA’s Goddard Space Flight Center Gamma rays make up a considerable amount of the cosmos. They can be […] Novae typically originate in binary systems containing Sun-like stars, as shown in this artist’s rendering. NASA’s Fermi Space Telescope discovered that a nova in a system like this likely produces gamma rays (magenta) through collisions among multiple shock waves in the rapidly expanding shell of debris. Image Credit: NASA’s Goddard Space Flight Center/S. […] A view of the entire gamma-ray sky from the Fermi Space Telescope, shaded to emphasize the center of the Milky Way. The inset is a map of the galactic center with known sources removed, which reveals the gamma-ray excess (red, green, and blue) found there. This excess emission is consistent with annihilations from […] The maps in this animation show how the sky looks at gamma-ray energies above 100 million electron volts (MeV) with a view centered on the north galactic pole. The first frame shows the sky during a three-hour interval prior to GRB 130427A. The second frame shows a three-hour interval starting 2.5 hours before […] The maps in this animation show how the sky looks at gamma-ray energies above 100 million electron volts (MeV), with a view centered on the north galactic pole. The first frame shows the sky during a three-hour interval prior to GRB 130427A. The second frame shows a three-hour interval starting 2.5 hours before […] Prior to its strong outbursts in 2011, blazar 4C +71.07 was a weak source for Fermi’s LAT. These images centered on 4C +71.07 show the rate at which the LAT detected gamma rays with energies above 100 million electron volts (lighter colors equal higher rates). The image at left covers 2.5 years, from […] Image Credit: NASA WASHINGTON — After more than three years in space, NASA’s Fermi Gamma-ray Space Telescope is extending its view of the high-energy sky into a largely unexplored electromagnetic range. Today, the Fermi team announced its first census of energy sources in this new realm. […] |

Another Look at Fermi’s Paradox
If intelligent alien life is so abundant, then where is it? Image Credit: NASA / HST
Enrico Fermi was a theoretical and experimental physicist known for his work on the first nuclear reactor and his contributions to quantum theory, particle physics, and statistical mechanics. He won the Nobel Prize in 1938 and was […]
