Research effort deep underground could sort out cosmic-scale mysteries
(DOE/Oak Ridge National Laboratory) The Department of Energy's Oak Ridge National Laboratory has begun delivery of germanium-76 detectors to an underground laboratory in South Dakota in a team research effort that might explain the puzzling imbalance between matter and antimatter generated by the Big Bang.
Frontiers launches new open-access journal in physics
(Frontiers) Frontiers in Physics is the latest journal to be launched as part of Frontiers' drive to bring its publishing model and research networking platform to all academic communities Frontiers in Physics is the latest journal to be launched as part of Frontiers' drive to bring its publishing model and research networking platform to all academic communities.
Detection of the cosmic gamma ray horizon: Measures all the light in the universe since the Big Bang
(University of California High-Performance AstroComputing Center) Radiation from all galaxies that ever existed suffuses the Universe with a diffuse extragalactic background light (EBL). Measuring the EBL is as fundamental to cosmology as measuring heat from the Big Bang (cosmic microwave background) at radio wavelengths. Alberto Dominguez and six coauthors describe the best measurement yet of the evolution of the EBL over the past 5 billion years, based on observations from radio waves to gamma rays from NASA spacecraft and ground-based telescopes.
Astronomers measure the elusive extragalactic background light
(University of California - Riverside) Measuring the extragalactic background light (EBL) is no simple task, complicated by the fact that Earth is lodged inside a bright solar system and a bright Milky Way. Now a team of astronomers has come up with a solution that ingeniously overcomes the technical challenges of measuring EBL. The researchers propose that one answer to the problem of measuring EBL lies in measuring the attenuation -- or weakening -- of very high-energy gamma rays from distant blazars.
Hubble reveals the Ring Nebula's true shape
(NASA/Goddard Space Flight Center) The Ring Nebula's distinctive shape makes it a popular illustration for astronomy books. But new observations by NASA's Hubble Space Telescope of the glowing gas shroud around an old, dying, sun-like star reveal a new twist.
Yuan Ping receives DOE Early Career Research Program Award
(DOE/Lawrence Livermore National Laboratory) Lawrence Livermore National Laboratory physicist Yuan Ping has been selected as a recipient of a Department of Energy Office of Science Early Career Research Program award. These awards provide $2.5 million over five years to support the development of individual research programs of outstanding scientists early in their careers and stimulate research careers in disciplines supported by the DOE Office of Science.
A hidden population of exotic neutron stars
(Chandra X-ray Center) Magnetars -- the dense remains of dead stars that erupt sporadically with bursts of high-energy radiation -- are some of the most extreme objects known in the Universe. A major campaign using NASA's Chandra X-ray Observatory and several other satellites shows magnetars may be more diverse -- and common -- than previously thought.
Bacterium from Canadian High Arctic offers clues to possible life on Mars
(McGill University) The recent discovery by a McGill University led team of scientists of a bacterium that is able to thrive at -15ºC, the coldest temperature ever reported for bacterial growth, is exciting because it offers clues about some of the necessary preconditions for microbial life on Mars.
U Alberta teams with citizen researchers 370 light years from Earth
(University of Alberta) A University of Alberta physicist brought together back-yard astronomers and professionals to confirm the mysterious behaviour of two stars more than 300 light years from Earth.
ESO's Very Large Telescope celebrates 15 years of success
(ESO) With this new view of a spectacular stellar nursery ESO is celebrating 15 years of the Very Large Telescope -- the world's most advanced optical instrument. This picture reveals thick clumps of dust silhouetted against the pink glowing gas cloud known to astronomers as IC 2944. These opaque blobs resemble drops of ink floating in a strawberry cocktail, their whimsical shapes sculpted by powerful radiation coming from the nearby brilliant young stars.
