NASA will hold a news teleconference at 2 p.m. EDT on Wednesday, Oct. 28, to discuss the first-year science results from the Fermi Gamma-ray Space Telescope. This event replaces the originally scheduled Oct. 29 media conference at NASA Headquarters in Washington. Fermi studies gamma rays, the highest-energy form of light. Findings discussed will include measurements relevant to the search for new theories of gravity. The panelists are: - Jon Morse, director, Astrophysics Division, NASA...

Scientists at the Naval Research Laboratory (NRL) Space Science Division and a team of international researchers have positively identified cosmic sources of gamma-ray emissions through the discovery of 16 pulsating neutron stars. Using the Large Area Telescope (LAT), the primary instrument on NASA's Fermi Gamma-ray Space Telescope satellite, the discoveries were made by conducting blind frequency searches on the sparse photon data provided by the LAT. The photons had energies between 20...

NASA's Fermi Gamma-ray Space Telescope is making some exciting discoveries about cosmic rays and the Large Area Telescope aboard Fermi is the tool in this investigation. Scientists in the Naval Research Laboratory's (NRL's) Space Science Division were instrumental in the design and development of the Large Area Telescope (LAT).Cosmic rays are electrons, positrons, and atomic nuclei that move at nearly the speed of light. Astronomers believe that the high-energy cosmic rays originate from...

Back in June 1991, just before the launch of NASA's Compton Gamma-Ray Observatory, astronomers knew of gamma rays from exactly one galaxy beyond our own. To their surprise and delight, the satellite captured similar emissions from dozens of other galaxies. Now its successor, the Fermi Gamma-ray Space Telescope, is filling in the picture with new finds of its own."Compton showed us that two classes of active galaxies emitted gamma rays -- blazars and radio galaxies," said Luigi Foschini at...

WASHINGTON, July 2 /PRNewswire-USNewswire/ -- With NASA's Fermi Gamma-ray Space Telescope, astronomers now are getting their best look at those whirling stellar cinders known as pulsars. In two studies published in the July 2 edition of Science Express, international teams have analyzed gamma-rays from two dozen pulsars, including 16 discovered by Fermi. Fermi is the first spacecraft able to identify pulsars by their gamma-ray emission alone. (Logo:...

NASA's Fermi Gamma-ray Space Telescope -- able to identify pulsars by gamma-ray emissions -- has provided data for two studies, U.S. officials said. International teams of astronomers say they've analyzed gamma-rays from two dozen pulsars, including 16 discovered by Fermi. A pulsar is the rapidly spinning and highly magnetized core left after a massive star explodes, NASA said. Since the demise of the Compton Gamma Ray Observatory a decade ago, we've wondered about the nature of unidentified...

A new class of pulsars detected by NASA's Fermi Gamma-ray Space Telescope is solving the mystery of previously unidentified gamma-ray sources and helping scientists understand the mechanisms behind pulsar emissions.A study to be published by an international team of scientists in the July 2 edition of Science Express describes 16 pulsars discovered by Fermi based on their pulsed emissions of high-energy gamma rays. A pulsar is a rapidly spinning neutron star, the dense core left behind after...

At a recent physics seminar at the Department of Energy's Fermi National Accelerator Laboratory, Fermilab physicist Pat Lukens of the CDF experiment announced the observation of a new particle, the Omega-sub-b (ÃŽ©b). The particle contains three quarks, two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton and has about six times the proton's mass.The observation of this "doubly strange" particle, predicted by the Standard...
