    breaking: ‘Black widow’ pulsars consume their mates
    With a deadly embrace, ‘spidery’ pulsars devour their partners. One such pulsar is the first rapidly spinning black widow to be discovered using only gamma rays.

    breaking: Astrophysicists use lens to study black-hole jet
    Using an entire galaxy as a lens to look at an object in the far distance, researchers are learning more about powerful jets emitted when matter falls into a black hole.

    gallery: Fermi’s first five years
    In its first five years gazing at the gamma-ray sky, the Fermi Gamma-ray Space Telescope provided new insights into cosmic puzzles ranging from dark matter to blazars—and added a few new puzzles to the list.

    breaking: Cosmic rays born in supernova aftermath
    One hundred years after the discovery of cosmic rays, a team of particle astrophysicists has definitively determined one source of these abundant yet enigmatic particles.

    feature: Illuminating the dark universe
    The pursuit of dark matter and dark energy is one of the most exciting—and most challenging—areas of science. Now researchers think they’re beginning to close in.

    breaking: Stellar black widows entrap companion stars
    Of the hundreds of objects in the universe emitting gamma rays, two look to be "black widows," ancient stars extending their lives by sucking in material from companion stars. Stanford physicist Roger Romani is hot on the trail of these extreme stars.

    breaking: Social scientists: Far-flung physicists meet face-to-face
    A tidal wave of gamma-ray scientists swept into Monterey, California, for the Fourth International Fermi Symposium, and despite the idyllic photo of a lovely local beach that graced the event poster, they didn’t come for the sun and surf. They came for science—and some face time.

    breaking: Fermi telescope gazes through fog to count the stars
    A recent measurement of how many gamma rays make it through a cosmic “fog” of starlight reveals just how many stars there are in the universe.

    breaking: Astrophysicists discover natural particle collider in space
    This summer, particle astrophysicists studied a supernova remnant located about 3000 light years away and discovered what is best described as a particle collider in space.

    feature: Particle physics tames big data
    As science produces an ever-growing flood of information, researchers in many fields struggle with how to collect, store, manage and distribute “big data.” Perhaps they could learn a thing or two from particle physics, a field that's been awash in enormous data sets for decades.

    breaking: Gamma-ray telescope designer awarded 2012 Panofsky Prize
    William Atwood, a leading member of the Fermi Gamma-ray Space Telescope collaboration, will receive the 2012 W. K. H. Panofsky Prize in Experimental Particle Physics from the American Physical Society for his work as co-designer of the Large Area Telescope, the main instrument on Fermi, and for using the LAT to investigate the universe in gamma rays.

    breaking: Fermilab theorist sees dark matter evidence in public data
    In their analysis of public data from the Fermi Gamma-ray Space Telescope, Dan Hooper, Fermilab scientist, and Lisa Goodenough, a graduate student at New York University, report that very-high-energy gamma rays coming from the center of the Milky Way originate from dark-matter collisions.

    feature: Preserving the data harvest
    Canning, pickling, drying, freezing -- physicists wish there were an easy way to preserve their hard-won data so future generations of scientists, armed with more powerful tools, can take advantage of it. They've launched an international search for solutions.
