Day 11/11 #FermiScience: Gamma-Ray Bursts! Fermi detects the brightest explosions in the universe with the Gamma-ray Burst Monitor (see video) and the LAT, revealing how matter is accelerated to extreme velocities and how black holes form. #Fermi11
Day 10/11 #FermiScience: Sunshine and Moonglow! Fermi shows that the Moon outshines the Sun in #gammarays thanks to Cosmic Rays hitting its surface which is unprotected by a magnetic field. Since Cosmic Rays come from all directions, the gamma-ray Moon is always full. #Fermi11
Day 9/11 #FermiScience: Supernova Remnants! Observations by Fermi's Large Area Telescope have firmly identified gamma-ray emissions from 40 Supernova Remnants, and established that they accelerate cosmic rays. Pictured: Jellyfish Nebula #Fermi11
Day 8/11 #FermiScience: Extragalactic Background Light! Interactions of #gammarays with this cosmic fog made of all the ultraviolet, visible and infrared light stars have created, allow a deep probe of the universe's stellar content. #Fermi11
Day 7/11 #FermiScience: Diffuse Gamma Radiation! If you like bubbles, you’ll love The Fermi Bubbles, which may point to past evidence of outflow activity driven by the gigantic black hole at the center of the Milky Way galaxy. Read more here: https://t.co/vRC6nkSvKc #Fermi11
Sometimes we want to study a bunch of objects that do the same thing; sometimes we want to study one really bright object in a bunch of different ways. The Crab is the latter. We keep looking and it keeps generating new observations and raising new questions. #Fermi11
Day 6/11 #FermiScience: Pulsar Wind Nebulae! Fermi has only detected a few of these, but one you may recognize is the Crab Nebula. Long held to be the standard candle of high-energy astrophysics, it exhibits strong gamma-ray flares on time-scales as short as half a day. #Fermi11

Day 5/11 #FermiScience: Terrestrial Gamma-Ray Flashes! Fermi doesn’t just detect #gammarays from the furthest corners of our universe, it also detects them from Earth. Associated with lightning, these gamma-ray flashes also produce high-energy electrons and positrons. #Fermi11
Day 4/11 #FermiScience: Dark Matter! Fermi scans the universe for gamma rays in dwarf spheroidal galaxies. Fermi provides a unique way to search for dark matter indirectly by surveying a wide variety of astrophysical sources. Watch this video to learn more #Fermi11
Day 2/11 #FermiScience: Pulsars! Fermi has transformed pulsar science by studying the gamma-ray properties of over 250 pulsars. Imagine half a million Earths crushed into a magnetized ball the size of Washington, D.C., some spinning nearly 1000 times a second. Weird. #Fermi11
Happy birthday, @NASAFermi! We hope you can continue to do amazing science for many more years! #Fermi11
Happy 11th Birthday to the Fermi Gamma-ray Space Telescope! Tag us in your posts @NASAFermi with #Fermi11 as we celebrate some of the incredible scientific developments that have resulted from this mission.
This was an awesome day! Watch the beginning of 11 years of awesome science and the fun continues. We're nowhere near finished with exploring the gamma-ray sky. #Fermi11
Day 1/11 #FermiScience: Active Galactic Nuclei! Fermi has detected 3000+ of these galaxies (https://t.co/0djrUCVZQK) with extremely bright centers powered by material swirling around and ultimately falling into supermassive black holes. #Fermi11

🎂 Buon compleanno @NASAFermi!
Il telescopio spaziale per la rivelazione di raggi gamma, realizzato con un fortissimo contributo italiano grazie a ASI, INFN e INAF, festeggia oggi il suo undicesimo anno in orbita. #Fermi11
Did you use a hairdryer this morning? If so, you used about the same amount of energy (1500 watts) that Fermi uses to observe photons with energy levels thousands to hundreds of billions of times greater than what the unaided eye can see! #Fermi11
Fermi’s solar panels have a wingspan of 50 feet, about the length of a basketball court. It is about the size of a car. At 9,500 lbs, it is comparable to the heaviest SUVs, and much of that mass is in dense scintillating crystals in the LAT instrument. #Fermi11
Fermi orbits Earth at an altitude of 300 miles at 17,000 mph and it takes 96 minutes to complete 1 orbit. Curious where Fermi is right now? Check out Fermi’s location at this link https://t.co/iYL8pRqsXf #Fermi11
