SLAC Research Makes Science Magazine's Top 10 of 2013

Editors of the journal Science, published by the American Association for the Advancement of Science, have selected their annual Top 10 Science Breakthroughs of the Year. On the list: Work by SLAC researchers pinning down the origin of cosmic rays.

Mock Data, Real Science

In scientific circles, “mock” is not always a four-letter word. To test that they’re interpreting their massive amounts of data correctly, astrophysicists create even more data: “mock” data. And while that may be counterintuitive at first, it actually makes a surprising amount of sense.

Cosmos Seeded with Heavy Elements During Violent Youth

Traces of iron spread smoothly throughout a massive galaxy cluster tell the 10 billion-year-old story of exploding supernovae and fierce outbursts from supermassive black holes sowing heavy elements throughout the early cosmos.

Dark Energy Survey Begins

Word of the official beginning of the Dark Energy Survey (DES) starts a five-year clock on a meticulous mapping of one-eighth of the night sky by the Dark Energy Camera, mounted on the Victor M.

The Universe Through Fermi's Eyes

On June 11, 2008, what was then the Gamma-ray Large Area Space Telescope rode a Delta II rocket into low-Earth orbit. After two months of tests and checks and calibrations, on August 11, 2008, NASA declared GLAST open for business as astrophysics' premier eye on the gamma-ray sky. Five years, a name change, a near miss with a defunct Soviet spy satellite, and countless surprises later, the spacecraft now known as the Fermi Gamma-ray Space Telescope is still going strong, with another five-year mission stretching ahead of it.

KIPAC Theorists Weigh In on Where to Hunt Dark Matter

Now that it looks like the hunt for the Higgs boson is over, particles of dark matter are at the top of the physics "Most Wanted" list. Dozens of experiments have been searching for them, but often come up with contradictory results.
