The news is that the Milky Way is bigger - if not as big as the Andromeda Galaxy - spinning faster, and we're much more likely to go splat in the deep future with Andromeda.

How would we "splat" against the Andromeda galaxy? Isn't that like light-years away from us?
It's 2.5 million (+/-) light years away. From what I understand, the Milky Way and Andromeda are spiraling in towards each other: the combined gravity of thw two galaxies is pulling them together.
It is supposed to be over a billion years from now - for some reason 2.5 billion sticks in my head - and look something like this when it happens.
Oh, and it won't be fast. Think of it like a cosmic train wreck that takes a looooong time (even in geological scales) to happen. The Antenna Galaxies began their crunch 500 million years ago and they're not done.
