The Nobel Prize in Physics 2002             Raymond Davis Jr and Masatoshi Koshiba have developed methods to detect cosmic neutrinos. Their discoveries have opened up the new field of neutrino astronomy – with large implications for particle physics, astrophysics and cosmology.           Contents: |  | …

  The Nobel Prize in Physics 2002           When you sunbathe, you also take a neutrino shower: 100,000 billion pass through your body every second. Statistically speaking, your body will stop only one of the many neutrinos which pass through it during a lifetime.   What makes the sun shine? Light…

  The Nobel Prize in Physics 2002   In the centre of our galaxy lies an X-ray source, the intensity of which can fluctuate wildly by the minute. Is this radiation emitted from matter that is falling into a super-massive black hole? The galaxy NGC 5128 is located 11 million light years from earth. What…
