Michael S. Witherell, Director of the U.S. Department of Energy’s Fermi National Acceleratory Laboratory, today (Nov. 1) announced the establishment of the Fermilab Particle Astrophysics Center, and named the renowned Fermilab and University of Chicago cosmologist Edward “Rocky” Kolb as its director.

Combining the newest of astronomical instruments with the most venerable techniques of patient attention to detail, scientists at the Department of Energy’s Fermi National Accelerator Laboratory, the University of Chicago and other institutions believe they have made the first optical observation of a gamma ray burst afterglow unprompted by prior observation of the gamma ray burst itself-a so-called “orphan afterglow.”

At a collaboration meeting in San Rafael, Argentina, scientists of the Pierre Auger Project, whose goal is to discover the source of very high-energy cosmic rays, today (September 13) announced the choice of the project’s northern-hemisphere observatory.

Scientists of the Pierre Auger Project, whose goal is to discover the source of very high-energy cosmic rays, will announce the choice of the project’s northern-hemisphere observatory at a meeting in San Rafael, Argentina on September 12. The 150-member collaboration will choose among three sites: one in western Spain, one in the western U.S., and one in Mexico.
