One of NASA's YouTube channels has published a "cosmological simulation" that "follows the development of a single disk galaxy over about 13.5 billion years.
NASA says the simulation was run on its Pleiades supercomputer at the Ames Research Center in Moffett Field, Calif, and required about 1 million CPU hours.
Sadly, there's no soundtrack to the simulation, but I'm sure the rest of the Internet will take care of that, and we'll soon get to see this to the strains of Boots Randolph's "Yakety Sax".
