Cosmic collision billions of years off could fling Earth out of Milky Way

Day to day here on Earth, our biggest threat from space is probably some undetected asteroid smashing into us, but astrophysicists looking at the universe on a much larger scale warn that another kind of collision could also impact our planet in the distant future.
A team led by researchers from the UK's Durham University says the threat of another galaxy colliding with the Milky Way could happen much sooner than previously thought and might send our entire solar system hurtling off in a new direction.
"There is a small chance that we might not escape unscathed from the collision between the two galaxies which could knock us out of the Milky Way and into interstellar space," Marius Cautun, a postdoctoral fellow at Durham's Institute for Computational Cosmology, said in a statement.
Cautun is lead author of a paper being published Friday in the journal Monthly Notices of the Royal Astronomical Society.
