    Long Beach, CA - Fasten your seat belts -- we're faster, heavier, and more likely to collide than we thought. Astronomers making high-precision measurements of the Milky Way say our Galaxy is rotating about 100,000 miles per hour faster than previously understood. That increase in speed, said Mark Reid of the Harvard-Smithsonian Center for Astrophysics, increases the Milky Way's mass by 50 percent, bringing it even with the Andromeda Galaxy. "No longer will we think of the Milky Way as the little sister of the Andromeda Galaxy in our Local Group family." The larger mass, in turn, means a greater...

    Astronomers have detected a pair of supermassive black holes that are closer together than any previously discovered. The two giants are dancing around each other with only about 24-light-years between them and are expected to collide in the very distant future. "That's more than 100 times closer than any pair found before," said astronomer Cristina Rodriguez from the University of New Mexico and Simon Bolivar University in Venezuela. Rodriguez was part of the team made the discovery using the National Science Foundation's Very Long Baseline Array (VLBA), a continent wide system of 10 linked radio-telescopes. The finding was announced today....
