Cosmic rays enter the "dark" age |
Cosmic rays enter the "dark" age (Mar 24)
http://physicsweb.org/article/news/9/3/16
Eight new sources of very high energy gamma rays have been found in the
centre of our galaxy, including two "dark" sources that have never been
seen before at other wavelengths. The discovery was made by an
international team of astrophysicists who used the HESS array of
telescopes in Namibia in Africa to conduct the most sensitive ever
survey of the Milky Way at such short wavelengths (F Aharonian et al.
2005 Science 307 1938). The results could help shed more light on the
origins of cosmic rays in the universe.
