      "(SPACE.com) -- A new survey of stars near the sun reveals a wild and crazy
      past in which wanderers arrived from all directions under the gravitational
      influences of black holes, clouds of gas and invading galaxies.

      European astronomers spent 15 years making 1001 nights of observations to
      detail the motions of more than 14,000 stars that are currently in the solar
      neighborhood, a tiny corner of the Milky Way. Tracing the movements back in time
      with a computer, the researchers found that most of the stars were once much
      farther from the sun than they are today.

      While astronomers expected the early history of the Milky Way was quite
      chaotic, most had believed "that it since had been rather calm," said study leader
      Birgitta Nordstrom of the Niels Bohr Institute for Astronomy, Physics, and
      Geophysics in Copenhagen. "But this turns out not to be true. Stars have been
      perturbed all the time throughout the Milky Way history."
