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.

Simulation: Chris Mihos (CWRU) & Lars Hernquist (Harvard).
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.
Buster Keaton’s Grand Slam Opera (1936) directly references a scene from the wildly successful Fred Astaire/Ginger Rogers film Top Hat (1935). In an attempt to let Ginger’s character sleep in the room below, Fred performs a soft shoe by laying sand beneath his taps, becoming her ‘sandman’. In Grand Slam Opera, Buster does the same, though was a far better comedian than he was a dancer.

If Hollywood had its own Mount Rushmore, Cary Grant’s profile would be the most prominent: the hair that Katharine Hepburn mussed in Bringing Up Baby (1938), the eyes that Eva Marie Saint couldn’t quite meet in North by Northwest (1959), the lips that locked so breathtakingly with Ingrid Bergman’s in Notorious (1946), and, of course, the cleft chin that fascinated Audrey Hepburn in Charade (1963).—EW’s 100 Greatest Movie Stars of All Times
