A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe.
An international team of astronomers, using NASA's Fermi observatory, has made the first-ever gamma-ray measurements of a gravitational lens, a kind of natural telescope formed when a rare cosmic alignment allows the gravity of a massive object to bend and amplify light from a more distant source.
During its five-year primary mission, NASA's Fermi Gamma-ray Space Telescope has given astronomers an increasingly detailed portrait of the universe's most extraordinary phenomena, from giant black holes in the hearts of distant galaxies to thunderstorms on Earth.
Astronomers have measured the light from the very earliest stars, working out for the first time the total amount of light from all the stars that have ever shone.
Physicists say they've found more evidence for the existence of dark matter, in the form of gamma rays emanating from the center of the galaxy.
The solar flare which erupted on March 7 was the most powerful eruption ever observed by Fermi's Large Area Telescope (LAT).
Nvidia is showcasing two new Kepler-powered Tesla GPUs at its annual GPU Technology Conference in San Jose, California.
Scientists have narrowed down the range in which dark matter could exist, thanks to a new analysis technique.
Nvidia recently debuted its long-awaited Kepler GPU lineup, which is based on 28-nanometer (nm) process technology and succeeds the 40-nm Fermi.
Nvidia has rolled out the first GPUs powered by its next-generation Kepler architecture, which is based on 28-nanometer (nm) process technology and succeeds the 40-nm Fermi.
Detectable for only a few seconds but possessing enormous energy, gamma-ray bursts are notoriously difficult to capture as their energy does not penetrate the Earth's atmosphere.
Nvidia has debuted its long-awaited GeForce GTX 590. The card - which targets "über" hardcore gamers - is powered by two Fermi-class GPUs on a single board.
Scientists have for the first time discovered that antimatter is regularly being produced on Earth - by thunderstorms.
NASA's Fermi Gamma-ray Space Telescope has discovered a massive structure spreading halfway across the Milky Way.
Nvidia has debuted its long-awaited, Fermi-powered GeForce GTX 580. The graphics card - which was reengineered from the transistor-level up - offers significantly optimized performance for DX11 gaming.
Welcome to Endless City! This gothic, film noir demo - which artfully blends computation and graphics - was created to showcase Fermi’s advanced tessellation capabilities.
