Fermi Space Telescope Explores New Energy Extremes


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. Today, the Fermi team announced its first census of energy sources in this new realm.

Fermi Detects 'Shocking' Surprise from Supernova's Little Cousin


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. The discovery overturns the notion that novae explosions lack the power to emit such high-energy radiation.

Fermi Gamma-ray Space Telescope and H.E.S.S. observe the blazar PKS 2155-304


An international team of astrophysicists using telescopes on the ground and in space have uncovered surprising changes in radiation emitted by an active galaxy. The picture that emerges from these first-ever simultaneous observations in visible light, X-rays and gamma rays is much more complex than scientists expected and challenges current theories of how the radiation is generated.

GLAST launched!


Stay updated on what is going on with GLAST by reading this GLAST blog !

Launch now set for 11 June 2008


Don't forget to check NASA's Shuttle and Rocket Missions for upcoming missions.

With GLAST launched there are opportunities for students to work with us in the field of high-energy/particle astrophysical processes, data analysis or computer science. Again, contact us for more information.

GLAST at the LLR


Welcome to homepage of the GLAST LLR/IN2P3/CNRS group. The GLAST project (Gamma-ray Large Area Space Telescope) is an astrophysics and astro-particle physics partnership exploring the high energy gamma-ray universe. This mission is a part of the NASA Office of Space and Science Strategic Plan, with launch planned in 2008.

The satellite has a main instrument (the Large Area Telescope, LAT) based on silicon strip detectors and a CsI Calorimeter, designed for making observations of cosmic gamma-ray sources with energy between about 30 MeV to 200 GeV. The French collaboration is contributing in the LAT calorimeter subsystem and funded by IN2P3/CNRS. The LLR has participated in the design and development of a hodoscopic CsI calorimeter for GLAST.

The GLAST project is funded in the US by NASA and the Department of Energy, and by government agencies in France, Italy, Japan, and Sweden. The GLAST project follows in the footsteps of the CGRO-EGRET mission.
