The highest circle of spiraling powers

Steve comments on the structural similarity of hurricanes and galaxies.

Here is Ivan whirling towards Jamaica, and the face-on spiral galaxy NGC 1232 in the constellation Eridanus (I've flipped its direction of rotation).

The galaxy is roughly 3 quadrillion times larger than the hurricane (that's 3 with 15 zeros). It is 70 million light-years away. The similarity does indeed suggest a deep universality to the laws of nature.

(I'll let Tom google my title.)
