Cassini Sheds Light On Cosmic Particle Accelerators
Pasadena CA (JPL) Feb 21, 2013
During a chance encounter with an unusually strong blast of solar wind arriving at Saturn, the international Cassini spacecraft detected particles being accelerated to ultra-high energies, similar to the acceleration that takes place around supernova explosions. Shock waves are commonplace in the universe, for example in the aftermath of a stellar explosion as debris accelerates outwards in a supernova remnant, or when the flow of particles from the Sun - the solar wind - impinges on the magneti ... read more
