During a powerful solar blast March 6/7, NASA’s Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the Sun. The discovery heralds Fermi’s new role as ...

With NASA’s Fermi Gamma-ray Space Telescope, astronomers now are getting their best look at those whirling stellar cinders known as pulsars. In two studies published in the July 2 edition of Science ...

If our eyes could see high-energy radiation called gamma rays, the Moon would appear brighter than the Sun! That’s how NASA’s Fermi Gamma-ray Space Telescope has seen our neighbor in space for the ...

Cosmic fireworks, invisible to our eyes, fill the night sky. We can get a glimpse of this elusive light show thanks to the Large Area Telescope (LAT) aboard NASA’s Fermi Gamma-ray Space Telescope, ...

The third release of the Fermi Point Source Catalog (4FGL-DR3) covers 12 years of data taken by the Large Area Telescope (LAT) on board of the Fermi Gamma-ray Space Telescope Fermi-LAT collaboration ...

Major improvements to methods used to process observations from NASA’s Fermi Gamma-ray Space Telescope have yielded an expanded, higher-quality set of data that allows astronomers to produce the most ...

A long time ago in a galaxy half the universe away, a flood of high-energy gamma rays began its journey to Earth. When they arrived in April, NASA’s Fermi Gamma-ray Space Telescope caught the outburst ...

After more than three years in space, NASA’s Fermi Gamma-ray Space Telescope is extending its view of the high-energy sky into a largely unexplored electromagnetic range. This week, the Fermi team ...

The gamma-ray sky comes alive in a movie made from data acquired by NASA’s Fermi Gamma-ray Space Telescope during its first three months of operations. Gamma rays from sources near and far turn the ...

Watch a cosmic gamma-ray fireworks show in this animation using just a year of data from the Large Area Telescope (LAT) aboard NASA’s Fermi Gamma-ray Space Telescope. NASA’s Marshall Space Flight ...
