Starship Asterisk*

Parts of this "belly band" had been spotted in Voyager images as a line of bright moutain peaks -- now referred to as the Voyager mountains -- jutting above the dark terrain along the equator. No other solid-surfaced body in the solar system has a self-defined equator.

It was discovered long before 2004 guys, , , duhhhhh

Equatorial bulges may be mysterious, but they are not exactly rare. Check out "moqui marbles" with Google. Notice the comparison to the blueberries on Mars.

The two images are too far apart to be seen as one clearly (using 3-D glasses), at least for me.

The 3D effect did work for me using red/blue glasses but it was not one of the best 3D images that I've seen on an APOD as there seemed to be too much red to the left. However, on clicking Patrick Vantuyne this brought up an amazingly effective 3D image (not astronomy related). It's worth seeing for anybody that has not already done so.

I'm confused.
In the caption for this image the height of the equitorial bulge is stated at 10 km. but in the previous image "Iapetus: 3D Equitorial Ridge: http://antwrp.gsfc.nasa.gov/apod/ap070915.html it is stated as 20 km.
Could it be shrinking this fast?
