“The ultimate objective of comparative planetology, it might be said, is something like a vast computer program into which we insert a few input parameters (perhaps the initial mass, composition and angular momentum of a protoplanet and the population of neighboring objects that strike it) and then derive the complete evolution of the planet.” Carl…

NASA/JPL NEWS RELEASE Posted: March 29, 2001 Kinks in the Sun’s magnetic field have puzzled scientists since they first started studying the solar wind, and now researchers at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., have found the reason: they are caused by the evolution of a type of magnetic wave called Alfven waves. Scientists measured…
