They're moving towards one of my theories, that I came up with in 1997 - not there yet, but see if I can get Emperor out first.
Anyway, here's the story:
Milky Way past was more turbulent than known
A team of astronomers from Denmark, Switzerland and Sweden has achieved a major breakthrough in our understanding of the Milky Way, the galaxy in which we live.
After more than 1,000 nights of observations spread over 15 years, they have determined the spatial motions of more than 14,000 solar-like stars residing in the neighbourhood of the Sun.
For the first time, the changing dynamics of the Milky Way since its birth can now be studied in detail and with a stellar sample sufficiently large to allow a sound analysis. The astronomers find that our home galaxy has led a much more turbulent and chaotic life than previously assumed.
