The "Supernova of a Generation" Shows Its Stuff

Marcus Woo

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.

More Clues in the Hunt for the Higgs

Marcus Woo

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.
