Lecture: The Fermi Gamma-ray Space Telescope: Opening a Window on the Extreme Universe

Date: Tuesday, April 18, 2017

Location: Pickford Theater, third floor, Madison Building, Library of Congress, DC, US, Washington

The public is invited to a free talk called "The Fermi Gamma-ray Space Telescope: Opening a Window on the Extreme Universe" with NASA's Dr. Julie McEnery in the Pickford Theater, third floor, Madison Building, Library of Congress, Washington, D.C., on April 18 from 11:30 a.m. to 12:30 p.m. EST.

Julie McEnery is the Fermi project scientist and an astrophysicist in the Astroparticle Physics Laboratory, Astrophysics Science Division of NASA's Goddard Space Flight Center in Greenbelt, Maryland. Since 2009, she has also been an adjunct professor of physics at the University of Maryland's College Park campus.

The Fermi Gamma-ray Space Telescope, launched in June 2008, provides a dramatic new view of the celestial sky. Fermi has changed our picture of the extreme universe, revealing gigantic lobes of gamma rays in our own galaxy, uncovering scores of rapidly spinning super-dense stars shining only in gamma rays, observing flashes of gamma rays heralding the birth of black holes at the edge of our observable universe, and detecting antimatter from thunderstorms on Earth. Join us for a tour of the energetic universe!

Gamma rays are the highest-energy form of light, and the gamma-ray sky is spectacularly different from the one we perceive with our own eyes. Fermi enables scientists to answer persistent questions across a broad range of topics, including supermassive black-hole systems, pulsars, the origin of cosmic rays, and searches for signals of new physics.

The Library of Congress maintains one of the largest and most diverse collections of scientific and technical information in the world. The Science, Technology and Business Division provides reference and bibliographic services and develops the general collections of the library in all areas of science, technology, business and economics.

The Library of Congress is the nation's oldest federal cultural institution and the largest library in the world and holds nearly 151.8 million items in various languages, disciplines and formats. The library serves Congress and the nation both on-site in its reading rooms on Capitol Hill and through its award-winning website.
