Swift survey finds 'missing' active galaxies
Seen in X-rays, the entire sky is aglow. Even far away from bright sources, X-rays originating from beyond our galaxy provide a steady glow in every direction. Astronomers have long suspected that the chief contributors to this cosmic X-ray background were dust-swaddled black holes at the centers of active galaxies. View News Article (2011-01-21)


CT scans better than X-rays when detecting abnormalities in patients with H1N1 virus
Computed tomography (CT) scans are better than standard radiography (X-rays) in showing the extent of disease in patients with the H1N1 virus. View News Article (2009-10-21)


Meteorite grains divulge Earth's cosmic roots
The interstellar stuff that became incorporated into the planets and life on Earth has younger cosmic roots than theories predict. View News Article (2009-06-16)


Detection of the cosmic gamma ray horizon: Measures all the light in the universe since the Big Bang
How much light has been emitted by all galaxies since the cosmos began? After all, every photon (particle of light) from ultraviolet to far infrared wavelengths ever radiated by all galaxies that ever existed throughout cosmic history is still speeding through the Universe today.  View News Article (2013-05-24)


Sun's rotating 'magnet' pulls lightning towards UK
The Sun may be playing a part in the generation of lightning strikes on Earth by temporarily 'bending' the Earth's magnetic field and allowing a shower of energetic particles to enter the upper atmosphere. View News Article (2014-11-20)


H.E.S.S. finds three extremely luminous gamma-ray sources
Wits scientists are part of a multinational team of astronomers working on the High Energy Stereoscopic System (H.E.S.S.) telescopes that have again demonstrated its excellent capabilities in searching for high-energy gamma rays. View News Article (2015-01-26)


Missions to Mars
The European Space Agency (ESA) has chosen the GSI accelerator facility to assess radiation risks that astronauts will be exposed to on a Mars mission. View News Article (2008-04-15)


Nanoparticles show promise as inexpensive, durable and effective scintillators
A team of industrial and university researchers has shown that nanoparticles with sizes smaller than 10 nanometers - approximately the width of a cell membrane - can be successfully incorporated into scintillation devices capable of detecting and measuring a wide energy range of X-rays and gamma rays emitted by nuclear materials.  View News Article (2013-03-26)


NASA Instrument Determines Hazards of Deep-Space Radiation
Deep-space radiation is a significant danger for interplanetary human space flight. But now an instrument on NASA's Lunar Reconnaissance Orbiter (LRO) has learned more than ever before about the high-energy hazards at and around the moon. New findings from the Cosmic Ray Telescope for the Effects of Radiation (CRaTER) were published today in the journal Space Weather. View News Article (2013-11-19)


Cosmic radiation associated with risk of cataract in airline pilots
Airline pilots have an increased risk of nuclear cataracts-common type of cataract, associated with aging-compared with non-pilots, and that risk is associated with cumulative exposure to cosmic radiation. View News Article (2005-08-09)
