Andromeda’s collision course with the Milky Way

I posted a warning about the threat from Andromeda in another thread recently but here is a nice presentation.

Andromeda’s collision course with the Milky Way: This Week in Astronomy with Dave Eich

At 300Km per second!

Quote:

Don’t look now, but a head-on intergalactic collision is in our distant future. From observations, astronomers know that the Andromeda Galxay (M31) — the nearest large galaxy — is moving toward our own Milky Way. Their mutual gravitational pull makes a galaxy merger inevitable, starting some 4 billion years from now.

Just something extra to add to our list of worries -- if I should live so long.
