Cosmic ray astrophysics began in 1912 when Victor Hess established that an extraterrestrial (and nonsolar) source of ionization inundates the Earth. More than a century later, a combination of remote sensing and in situ observations have built up a picture of cosmic rays as an important sink of supernova energy and a major constituent of the interstellar medium. I will review our current state of knowledge of cosmic rays, describe some heliospheric and laboratory analogs, and  discuss some ongoing research.

Will this event be webcast to the public by NCAR|UCAR?:
