This poster summarizes the career to date of NASA's Fermi Gamma-ray Space Telescope. The central image is a map of the whole sky at gamma-ray wavelengths accumulated over six years of operations. The poster also discusses other Fermi findings, including a black widow pulsar, the Fermi Bubbles rising thousands of light-years out of our galaxy's center, a giant gamma-ray flare from the Crab Nebula, and many more.

What is Fermi?

General Dynamics C4 Systems - Artist Concept of Fermi The Universe is home to numerous exotic and beautiful phenomena, some of which can generate almost inconceivable amounts of energy. Supermassive black holes, merging neutron stars, streams of hot gas moving close to the speed of light ... these are but a few of the marvels that generate gamma-ray radiation, the most energetic form of radiation, billions of times more energetic than the type of light visible to our eyes. What is happening to produce this much energy? What happens to the surrounding environment near these phenomena? How will studying these energetic objects add to our understanding of the very nature of the Universe and how it behaves?

The Fermi Gamma-ray Space Telescope, formerly GLAST, is opening this high-energy world to exploration and helping us answer these questions. With Fermi, astronomers at long last have a superior tool to study how black holes, notorious for pulling matter in, can accelerate jets of gas outward at fantastic speeds. Physicists are able to study subatomic particles at energies far greater than those seen in ground-based particle accelerators. And cosmologists are gaining valuable information about the birth and early evolution of the Universe.

For this unique endeavor, one that brings together the astrophysics and particle physics communities, NASA has teamed up with the U.S. Department of Energy and institutions in France, Germany, Japan, Italy and Sweden. General Dynamics was chosen to build the spacecraft. Fermi was launched June 11, 2008 at 12:05 pm EDT.

NASA's Fermi Telescope Helps Link Cosmic Neutrino to Blazar Blast

Nearly 10 billion years ago, the black hole at the center of a galaxy known as PKS B1424-418 produced a powerful outburst. Light from this blast began arriving at Earth in 2012. Now astronomers using data from NASA's Fermi Gamma-ray Space Telescope and other space- and ground-based observatories have shown that a record-breaking neutrino seen around the same time likely was born in the same event.

Two New Online Services

Two new online services have recently been added to the FSSC web site. The Fermi All-sky Variability Analysis (FAVA) employs a photometric technique to identify flaring sources in the Fermi LAT data and also offers a capability to for end users to compute light curves for any point on the sky for user specified time intervals. A second facility, maintained by the NASA Marshall Space Flight Center, provides a tabulation of candidate Untriggered GBM Short GRB Candidates. With the graphical and textual information provided, users can easily obtain the digital data from the FSSC data archive and perform their own detailed analyses.

NASA's Fermi Telescope Poised to Pin Down Gravitational Wave Sources

On Sept. 14, waves of energy traveling for more than a billion years gently rattled space-time in the vicinity of Earth. The disturbance, produced by a pair of merging black holes, was captured by the Laser Interferometer Gravitational-Wave Observatory (LIGO) facilities in Hanford, Washington, and Livingston, Louisiana. This event marked the first-ever detection of gravitational waves and opens a new scientific window on how the universe works.
