Located about 21 million light-years from our galaxy in the constellation Canes Venatici, NGC 4618 has a diameter of about one-third that of our Milky Way. Together with its neighbor, NGC 4625, it forms an interacting galaxy pair, which means that the two galaxies are close enough to influence each other gravitationally.

The arms emanate from a spinning core and "should" therefore become wound up ever more tightly over time. Instead, they move more slowly, like an interstellar traffic jam.
