Collision imminent!

Collision imminent!  A giant cloud of gas (weighing more than a million suns) is headed for the Milky Way galaxy at 700,000 MPH.  It will hit a different arm of the galaxy than the Earth is in, about 30 million years from now.  That's imminent in the grand scheme of things, though it may not seem so to you :)
