Astronomy Meeting Highlights

The DZero detector records particles emerging from high-energy proton-antiproton collisions produced by the Tevatron. For this measurement of CP violation, scientists analyzed 10 trillion collisions collected over the last eight years. Credit: Fermilab

From changing ideas of how black holes operate to a solar system that's decidedly off-kilter, we'll get somehighlights from the 216th meeting of the American Astronomical Society in Florida. Plus -- why is there stuff? New data from the Tevatron particle accelerator at Fermilab may point towards the answer. There seems to be an imbalance between the amounts of matter and antimatter in the universe.
