  The Nobel Prize in Physics 2002           The discovery of the first known X-ray source outside the solar system, Scorpius X-1. This observation was made in 1962, with an Aerobee rocket. X-ray background radiation was also detected.   Scorpius X-1 (artist’s impression) is a binary system consisting of a neutron…

  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…

  The Nobel Prize in Physics 2002           The Supernova 1987A Photo: The Anglo-Australian Observatory   What is a supernova? When the fusion reactions in a massive star end, it collapses and throws off its outer layers in a giant explosion. In just a few seconds, huge amounts of energy –…

  The Nobel Prize in Physics 2002           Raymond Davis Jr University of Pennsylvania, Philadelphia, USA, previously at Brookhaven National Laboratory, Upton, New York, USA. A neutrino produced an argon atom in the tank every other day.   ELUSIVE PARTICLES CAPTURED IN CLEANING FLUID Neutrinos rarely interact with matter and are…

  The Nobel Prize in Physics 2002           Riccardo Giacconi Associated Universities Inc., Washington, DC, USA Photo: National Radio Astronomy Observatory (NRAO)   On 18 June 1962, a new era in astronomy started when a rocket experiment demonstrated the presence of X-ray radiation outside the solar system. Leading the project was…

  The Nobel Prize in Physics 2002 The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2002 with one half jointly to Raymond Davis Jr and Masatoshi Koshiba “for pioneering contributions to astrophysics, in particular for the detection of cosmic neutrinos” and the other half to Riccardo Giacconi…
