Unruly Milky Way

empaler writes "Space.com is running a story about the movement history of the local group near our solar system. The belief until now has been that after an initial period of chaos in our galaxy, it had since 'been rather calm'. 'But this turns out not to be true. Stars have been perturbed all the time throughout the Milky Way history.'"

I wonder if they'll find anything to indicate dramatic climate changes, as has been speculated, due to radiation I think. Right now we're in the arm of Orion, which is a relatively calm place to be, but we (or should I say Sol) tends to drift a bit.
