Hit Me!
I have so many horrible things to write about you, and I’m not going to refrain from posting them because ‘you’re not worth it’, which you are not. But because what’s the point, you’re poison to me, I have no desire to pass anything but pleasantries between us.
Though I must admit I am curious as to why you’ve, once again, started stirring.
I lied.

Galaxy Collisions: Simulation vs Observations
The folks over at NASA apod just put up an awesome galaxy collisions, simulations and observations video for the public. I made a little gif set to go along with the video which can be found here.
What happens when two galaxies collide? Although it may take over a billion years, such titanic clashes are quite common.

Since galaxies are mostly empty space, no internal stars are likely to themselves collide. Rather the gravitation of each galaxy will distort or destroy the other galaxy, and the galaxies may eventually merge to form a single larger galaxy.
Expansive das and dust clouds collide and trigger waves of star formation that complete even during the interaction process. Pictured above is a computer simulation of two large spiral galaxies colliding, interspersed with real still images taken by the Hubble Space Telescope.
Our own Milky Way Galaxy has absorbed several smaller galaxies during its existence and is even projected to merge with the larger neighboring Andromeda galaxy in a few billion years.
