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.

Fermi Cycle 14 Proposal Deadline Extended

Owing to the severe weather situation and power outages in Texas and other areas NASA has decided to postpone the Fermi Cycle-14 proposal deadline until March 1, 2021, 16:30 EST. If you have already submitted a proposal you need not resubmit unless you wish to make changes which you may do up to the new deadline. Submission procedures are otherwise unchanged; refer to our website for details.

Fermi Cycle 14 Proposer Workshop

The deadline for Fermi Cycle 14 Guest Investigator proposals is coming soon: Feb 19 at 16:30 EST. To help you prepare your proposals, the project and science support center will host a virtual workshop to provide information about updates to the program (for example, preparing proposals for dual anonymous review) and to provide support for new proposers. Please register using this form by Feb 1 so that we can send you the details to join the virtual meeting.

NASA Missions Unmask Magnetar Eruptions in Nearby Galaxies

On April 15, 2020, a brief burst of high-energy light swept through the solar system, triggering instruments on several NASA and European spacecraft. Now, multiple international science teams conclude that the blast came from a supermagnetized stellar remnant known as a magnetar located in a neighboring galaxy.
