06.29.11 - Every 3.4 years, a pair of mismatched stars in the southern constellation Crux whisk past each other, shooting out extreme forms of light each time.
05.20.11 - Teams of researchers using radio telescopes have produced the most detailed image of particle jets erupting from a supermassive black hole.
05.11.11 - The Crab Nebula supernova remnant erupted in an enormous flare, five times more powerful than any flare previously seen from the object on April 12.
01.12.11 - The Crab Nebula was once thought to be the steadiest high-energy source in the sky. Not so, according to new data from NASA satellites.
01.10.11 - Scientists using NASA's Fermi Space Telescope have detected antimatter produced above thunderstorms on Earth, a phenomenon never seen before.
11.09.10 - NASA's Fermi Gamma-ray Space Telescope unveiled a previously unseen structure centered on the Milky Way. The feature spans 50,000 light-years.
10.14.10 - Julie McEnery and David Thompson of NASA's Fermi Space Telescope team have won the famous Lindsay award.
08.12.10 - Astronomers using NASA's Fermi Gamma-ray Space Telescope have detected gamma-rays from a nova for the first time, a finding that stunned observers and theorists alike because unlike supernovae, these explosions are typically too small to see.
04.01.10 - If our eyes could see radio waves, the nearby galaxy Centaurus A would be one of the biggest and brightest objects in the sky, nearly 20 times the apparent size of a full moon.
03.02.10 - Fermi reveals that most extragalactic gamma radiation comes from unknown sources rather than from black-hole-powered jets from active galaxies—what astronomers once considered the most likely suspects.
02.16.10 - New images of supernova remnants from NASA's Fermi Telescope bring astronomers a step closer to understanding the source of some of the universe's most energetic particles -- cosmic rays.
01.27.10 - Astronomers have found evidence that two supernovae blasts received an extra boost from newborn black holes.
01.05.10 - Radio astronomers have uncovered 17 millisecond pulsars in our galaxy that could be used as a kind of "galactic GPS" to detect gravitational waves passing near Earth.
12.08.09 - Thanks to a series of flares that began September 15, a galaxy located billions of light-years away is now the brightest object in the gamma-ray sky.
11.26.09 - The Fermi Telescope has made the first unambiguous detection of high-energy gamma-rays from an enigmatic binary system known as Cygnus X-3.
11.02.09 - Two 'starburst' galaxies, plus a satellite of our own Milky Way galaxy, represent a new category of gamma-ray-emitting objects detected both by Fermi and ground-based observatories.
10.28.09 - In one year of operation, NASA's Fermi Telescope has seen more than 1,000 sources of gamma-rays, but it still can't unseat Einstein's theory of relativity.
07.03.09 - With NASA's Fermi Gamma-ray Space Telescope, astronomers now are getting their best look at those whirling stellar cinders known as pulsars.
05.29.09 - Fermi, the successor to the Compton Gamma-Ray Observatory, is filling in the "gamma ray" picture with new finds of its own.
05.04.09 - Fermi scientists revealed new details about high-energy particles implicated in a nearby cosmic mystery.
