Fermi's 10th Anniversary
Fermi 10 year anniversary sticker.
June 11th was the 10th anniversary of the launch of the Fermi Gamma-ray Space Telescope! This exciting mission has revolutionized our understanding of the cosmos by observing the universe in gamma-rays, the most energetic kind of light. Thanks to Fermi, scientists have learned more about fundamental physics of the cosmos, from dark matter to the nature of space-time and beyond.

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 Traces Source of Cosmic Neutrino to Monster Black Hole

For the first time ever, scientists using NASA's Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. This neutrino traveled 3.7 billion years at almost the speed of light before being detected on Earth. This is farther than any other neutrino whose origin scientists can identify.

Fermi Resumes Science Operations

Both instruments on Fermi have been returned to operational status and are actively collecting science data. For the LAT, this data will be used to monitor performance as the instrument returns to normal operating temperatures. GBM has returned to full functionality.
