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)

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)

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)

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)

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)

CU-Boulder researchers use climate model to better understand electricity in the air
Electrical currents born from thunderstorms are able to flow through the atmosphere and around the globe, causing a detectable electrification of the air even in places with no thunderstorm activity. View News Article (2013-10-04)

NASA X-ray concept inspired from a roll of Scotch® tape
The inspiration behind NASA scientist Maxim Markevitch's quest to build a highly specialized X-ray mirror using a never-before-tried technique comes from an unusual source: a roll of Scotch® tape. View News Article (2012-07-27)

IBEX research shows influence of galactic magnetic field extends well beyond our solar system
In a report published today, new research suggests the enigmatic "ribbon" of energetic particles discovered at the edge of our solar system by NASA's Interstellar Boundary Explorer (IBEX) may be only a small sign of the vast influence of the galactic magnetic field. View News Article (2014-02-14)

High Energy Mystery lurks at the Galactic Centre
A mystery lurking at the centre of our own Milky Way galaxy - an object radiating high-energy gamma rays - has been detected by an international team of astronomers. Their research, published today (September 22nd) in the Journal Astronomy and Astrophysics, was carried out using the High Energy Stereoscopic System (H.E.S.S.), an array of four telescopes, in Namibia, South-West Africa. View News Article (2004-09-22)

Astrophysics and Extinctions: News About Planet-Threatening Events
Space is a violent place. If a star explodes or black holes collide anywhere in our part of the Milky Way, they'd give off colossal blasts of lethal gamma-rays, X-rays and cosmic rays and it's perfectly reasonable to expect Earth to be bathed in them. View News Article (2011-10-10)
