ESA -- Astronomers have witnessed a never-seen-before event in observations by ESA's XMM-Newton spacecraft -- a collision between a pulsar and a ring of gas around a neighbouring star. The rare passage, which took the pulsar plunging into and through this ring, illuminated the sky in gamma- and X-rays. It has revealed a remarkable new insight into the origin and content of 'pulsar winds', which has been a long-standing mystery. The scientists described the event as a natural but...

PPARC -- In a recent issue of Science Magazine, the High Energy Stereoscopic System (H.E.S.S.) team of international astrophysicists reports the discovery of another new type of very high energy (VHE) gamma ray source. Gamma-rays are produced in extreme cosmic particle accelerators such as supernova explosions and provide a unique view of the high energy processes at work in the Milky Way. VHE gamma-ray astronomy is still a young field and H.E.S.S. is conducting the first sensitive survey at...

PPARC --  In the March 25th 2005 issue of Science Magazine, the High Energy Stereoscopic System (H.E.S.S.) team of international astrophysicists, including UK astronomers from the University of Durham, report results of a first sensitive survey of the central part of our galaxy in very high energy (VHE) gamma-rays. Included among the new objects discovered are two 'dark accelerators' - mysterious objects that are emitting energetic particles, yet apparently have no optical or x-ray...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
