SUMMARY:Cosmic Rays: the most energetic particles in the universe
DESCRIPTION:Featuring Jim Cronin\, Nobel Laureate\, Enrico Fermi Institute 
	at the University of Chicago\nHosted by: Lawrence Sulak\n\nPart of the Phys
	ics Department Colloquia Series.\n\nDean S. Edmonds\, Sr. Memorial Lecture\
	n\nSingle cosmic rays can have enormous energies\, exceeding 20 joules each
	. This is a macroscopic energy packed in a microscopic particle. How Nature
	 accomplishes this has been a mystery for more than 45 years. Recent experi
	ments have attempted to solve this mystery\, but they have had to work with
	 a very low flux of these extremely high-energy cosmic rays – about o
	ne per km2 per century.  The Pierre Auger Observatory is a new detector add
	ressing this mystery. With a surface area of 3000 km2\, it detects the show
	er of particles produced by a primary cosmic ray both on the ground and by 
	the fluorescence light emitted in the atmosphere. Though the full observato
	ry will be complete by the end of 2007\, it has been recording cosmic rays 
	as it has grown since January 2004. Preliminary results\, as well as the pr
	ospects for the very near future\, will be presented.
