Michael Aschbacher, the Shaler Arthur Hanisch Professor of Mathematics, has been awarded the 2012 Leroy P. Steele Prize for Mathematical Exposition by the American Mathematical Society (AMS). Aschbacher, along with coauthors Richard Lyons of Rutgers University, Steve Smith of the University of Illinois at Chicago, and Ronald Solomon of Ohio State University, were recognized for a paper on the classification of certain types of groups, which are fundamental mathematical objects.

It was the brightest and closest stellar explosion seen from Earth in 25 years, dazzling professional and backyard astronomers alike. Now, thanks to this rare discovery—which some have called the "supernova of a generation"—astronomers have the most detailed picture yet of how this kind of explosion happens. Known as a Type Ia supernova, this type of blast is an essential tool that allows scientists to measure the expansion of the universe and understand the very nature of the cosmos.

Physicists have announced that the Large Hadron Collider (LHC) has produced yet more tantalizing hints for the existence of the Higgs boson. The European Center for Nuclear Research in Geneva, the international team of thousands of scientists—including many from Caltech—unveiled for the first time all the data taken over the last year from the two main detectors at the LHC, the Compact Muon Solenoid and ATLAS. The results represent the largest amount of data ever presented for the Higgs search.

Researchers have set a new world record for data transfer, helping to usher in the next generation of high-speed network technology. The international team was able to transfer data in opposite directions at a combined rate of 186 gigabits per second (Gbps) in a wide-area network circuit. The rate is equivalent to moving two million gigabytes per day, fast enough to transfer nearly 100,000 full Blu-ray disks—each with a complete movie and all the extras—in a day.

We've all heard that no two snowflakes are alike. Caltech professor of physics Kenneth Libbrecht will tell you that this has to do with the ever-changing conditions in the clouds where snow crystals form. Now Libbrecht, widely known as the snowflake guru, has shed some light on a grand puzzle in snowflake science: why the canonical, six-armed "stellar" snowflakes wind up so thin and flat.

Two new faculty members have joined the Division of Physics, Mathematics and Astronomy. Ryan Patterson, assistant professor of physics, studies the elusive neutrino, a mysterious particle that could hold the clues to some of the universe's biggest questions. Vladimir Markovic, professor of mathematics, is trying to understand the shapes and structures of mathematical spaces called manifolds. In particular, he's worked with a mathematical object that resembles a pair of pants.

Astronomers have detected massive quantities of water in a planet-forming gas disk around a young star. The water—which is frozen in the icy outer regions of the disk—could fill Earth's oceans several thousand times over. The discovery could help explain how Earth got its oceans and suggests that our planet may not be the only watery world in the cosmos.
