SLAC Public Lecture on the First Star in the Universe

What was the first thing in the universe—a black hole or a star? How did it form? Even our biggest and best telescopes cannot tell us. Direct calculation with supercomputers, however, can. The first luminous objects in the universe were very massive stars shining one million times as brightly as our sun. They died quickly and seeded the cosmos with the chemical elements necessary for life. One star at a time, galaxies started to assemble just one hundred million years after the Big Bang, and they are still growing now.

In tonight's public lecture, the Kavli Institute for Particle Astrophysics and Cosmology's Tom Abel will use the latest computer animations of early star formation, supernovae explosions, and the buildup of the first galaxies to take you on a fascinating journey through the early universe. The lecture takes place at 7:30 p.m. in the Panofsky Auditorium. All are invited to attend. Learn more...

Regulations for Making International Shipments

by Kelen Tuttle

All of SLAC's international shipments are required by federal regulations to undergo an export control process before leaving the site. This process includes classifying the items to determine if they require a special export license and running the names of the individual and institution to which the shipment is addressed through an export compliance screening program.

"Even though none of SLAC's work is classified because of the principle of openness in research, it's required that we follow Federal laws and regulations about exporting materials to other countries," said User Support and Records Manager Pamela Elliott.

In order to allow adequate time for the User Support group to properly classify and screen shipments, all SLAC employees and users are advised to allow 48 hours from submitting their shipper to final approval by User Support.

"More complicated shipments may require more time for screening, but we strive to keep the turn-around time as close to 48 hours as possible," Elliott said. User Support encourages the SLAC community to call for more information regarding this process.
