Sizing up black holes
ST. LOUIS—Astronomers are all wound up over a new method for sizing up supermassive black holes found at the cores of galaxies. The method allows researchers for the first time to estimate the weight of these black holes in spiral galaxies up to 8 billion light-years away, or halfway across the universe, reports Marc Seigar […]

Better view of the Milky Way
New studies revise the structure of the Milky Way, exchanging the old map of a four-armed spiral galaxy for a two-arm version. The makeover also includes the discovery of a smaller, short, gaseous arm that is a long-sought counterpart to a similar arm near the galaxy’s center.
