Nature Paper Describes Closest-ever Look at Explosion of Type Ia Supernova

Even as the "supernova of a generation" came into view in backyards across the northern hemisphere last August, physicists and astronomers who had caught its earliest moments were developing a surprising and much clearer picture of what happens during a titanic Type Ia explosion. Led by Peter Nugent of CRD's Computational Cosmology Center (C3), the team describes the closest, most detailed look ever at one of the universe's brightest "standard candles," the celestial mileposts that led to the discovery of dark energy in the Dec. 15 issue of the journal Nature. Rollin Thomas of C3 is a co-author of the paper. Read more.

NERSC's Steve Lowe: Driven to High Performance Machines

During his combined 29 years at Lawrence Livermore and Lawrence Berkeley national labs, Steve Lowe has worked with some of the most powerful computing machinery anywhere. And when he isn't at work, there aren't many things he'd rather do than figure out a way to squeeze more performance out of a muscle car like a Chevy Camaro or Pontiac Firebird. But come Jan. 3, he'll trade in his career and home in Tracy for a new lifestyle—retiring and spending a few years exploring North America with his wife in an RV. Read more about Steve's career.

When's the Next Lab Shuttle Due? Look Here

When the weather's cold and windy, waiting at the bus stop can be a chilling experience. Fortunately, a couple of online tools can help you plan your trip (and avoid running to catch the bus as it's pulling out).

Nextbus lets you pick the stop and see when the next bus is arriving and which route it's following.

Another Nextbus site provides a map of the lab and shows the location of buses on their routes.

About Computing Sciences at Berkeley Lab

The Lawrence Berkeley National Laboratory (Berkeley Lab) Computing Sciences organization provides the computing and networking resources and expertise critical to advancing the Department of Energy's research missions: developing new energy sources, improving energy efficiency, developing new materials and increasing our understanding of ourselves, our world and our universe.

ESnet, the Energy Sciences Network, provides the high-bandwidth, reliable connections that link scientists at 40 DOE research sites to each other and to experimental facilities and supercomputing centers around the country. The National Energy Research Scientific Computing Center (NERSC) powers the discoveries of 7,000-plus scientists at national laboratories and universities, including those at Berkeley Lab's Computational Research Division (CRD). CRD conducts research and development in mathematical modeling and simulation, algorithm design, data storage, management and analysis, computer system architecture and high-performance software implementation. NERSC and ESnet are Department of Energy Office of Science User Facilities.

Lawrence Berkeley National Laboratory addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the DOE’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit science.energy.gov.
