This movie shows an encounter between a gas rich disk galaxy
and a very high Mass-to-Light ratio gas poor dwarf galaxy. As this movie
shows the response of the gas (each colored dot is gas), the dwarf
galaxy does not appear in the movie, only its gravity is reflected.
This movie shows how the UV appearance of a galaxy, in this case
M81, and the Red appearance of the galaxy, are very different. The movie
begins with the UV and ends with the Red. The UV light comes from stars
that are about 1 million years old, the Red light comes from stars that
are 5 Billion years old.
