[If the video doesn’t play:
A white wolf runs along a coast, coming to a stop at the end of a strip of land that extends modestly out into the calm ocean. The wolf pauses in her run, looking up at the most prominent feature of the night sky--and no, it’s not the moon, but the
Whirlpool Galaxy. At 160 billion solar masses, it is much too close to have kept its grand spiral design in the presence of the larger Milky Way. For its 76,000 light-years diameter, it should be lighting up the entire night sky and not simply sparkling like any other star. Yet there it is, sitting as motionless as a pinwheel during a festival with no wind.
The moment the wolf sits down and looks up at this cosmic wonder, the galaxy begins to spin. It turns slowly at first, gathers momentum...and then the feed ends.]
