University of Chicago The National Aeronautics and Space Administration has awarded $4.4 million to a collaboration of scientists at five United States universities and NASA´s Marshall Space Flight Center to help build a telescope for deployment on the International Space Station in 2017. The U.S. collaboration is part of a 13-nation effort to build the 2.5-meter ultraviolet telescope, called the Extreme Universe Space Observatory. UChicago Prof. Angela Olinto leads the U.S....

Cosmic Ray Origins Still A Mystery

April Flowers for redOrbit.com - Your Universe Online In August, physicists will gather to celebrate a century of research since the discovery of cosmic rays. It is widely accepted that cosmic rays are the nuclei of atoms, from the full array of naturally occurring elements that travel at near-light-speeds for millions of years before reaching Earth. What isn't known yet is where these cosmic rays originate. Alan Watson, emeritus professor of physics at the University of Leeds, provides...

Physicists from UCLA and Japan have discovered evidence of "natural nuclear accelerators" at work in our Milky Way galaxy, based on an analysis of data from the world's largest cosmic ray detector. The research is published Aug. 20 in the journal Physical Review Letters. Cosmic rays of the highest energies were believed by physicists to come from remote galaxies containing enormous black holes capable of consuming stars and accelerating protons at energies comparable to that of a bullet shot...

With its powerful detectors, Integral has performed the most-sensitive all-sky survey ever, finding expected clumpy areas at large scales in our local universe. Scientists working with ground-based telescopes have found the same local clumps, while looking for sources of cosmic showers. Integral performed the survey in the hard X-ray band of the electromagnetic spectrum. Although it wasn't the first such survey, Integral's strength lies in the fact that it is unbiased towards sources that are...

ARGONNE, Ill. "“ Ultra-high-energy particles from just outside enormous, active black holes in nearby galaxies travel as far as 250 million light years to make it all the way to Earth, an international team of 400 physicists and astronomers from 17 countries reports in the Nov. 9 issue of the journal Science. "This is the dawn of a new type of astronomy, the beginning of ultra-high-energy-charged particle astronomy," said physics professor Katsushi Arisaka, who led the UCLA research...
