Unveiling spiral magnetism
Iron is the most useful magnet in our daily life. It is a ‘ferromagnet’ at room temperature and ambient pressure, but displays a variety of other magnetic…
Fermi maps an active galaxy's 'smokestack plumes'
NASA's Fermi Gamma-Ray Space Telescope maps gamma rays, radiation that typically packs 100 billion times the energy of radio waves. Nevertheless, and to the…
Fermi Sees Brightest-Ever Blazar Flare
Astronomers identify the object as 3C 454.3, an active galaxy located 7.2 billion light-years away in the constellation Pegasus. But even among active…
Rare Space Experiment Gives Clues About the Fundamental Structure of the Universe
The experiment was performed by a team that includes astrophysicists at Penn State University, who used NASA's Fermi Gamma Ray Space Telescope to study…
Fermi Large Area Telescope reveals pulsing gamma-ray sources
Using the Large Area Telescope (LAT), the primary instrument on NASA's Fermi Gamma-ray Space Telescope satellite, the discoveries were made by conducting blind…
NRL's Large Area Telescope explores high-energy particles
