An curved arrow pointing right. NASA's Fermi Gamma-ray Space Telescope can now detect solar flares occuring on the side of the sun it cannot see. This could help scientists better understand solar ...

Space is a big place and there's lots of strange stuff out there, but scientists aren't quite sure where these massive space bubbles came from.

With an effective area four times greater than the Fermi Gamma-ray Burst Monitor—the most ... which recently concluded a highly productive mission on the International Space Station, detecting ...

Fermi’s main instrument, the Large Area Telescope (LAT), thus operates more like a particle detector. When a gamma ray reaches the telescope, it impacts on a metal foil producing a pair of charged ...

One such observatory is the Fermi gamma-ray space telescope. NASA launched the car-size satellite in 2008, and it has been mapping a normally invisible side of the universe (shown above ...

The Moon outshines the Sun as cosmic rays bounce off its surface creating gamma radiation. They aren’t visible to the naked eye but were spotted using NASA’s Fermi Gamma Ray Telescope.
