Turbulent Moons

The many layers of Titan's atmosphereThere were quite a number of articles in the 31 January edition of the journal Nature that would be potential topics for a post from the ICR. These included the discovery of the bizarre underlying genetic mechanism (pdf) behind the two different social structures of the fire ant Solenopsis invicta, which has implications for the evolution of sex chromosomes; a review of a biography of Louis Agassiz, “a great science populariser who resisted Darwinism”; an obituary for Carl Woese (though we’ve already looked at that topic); and some rigid biomemetic polymers, a field which creationists adore. But the article that Jake Hebert – yes, him again – has written about is a feature called Caught in the act. “We may be seeing some of the Solar System’s most striking objects during rare moments of glory.” His own article is called Youthful Solar System Bodies Puzzle Evolutionary Scientists.

A feature story in a recent issue of the journal Nature described four solar system bodies that are puzzling to evolutionary scientists. Specifically, the article discussed the rings of Saturn, two of Saturn’s moons (Enceladus and Titan), and Jupiter’s moon Io. These four bodies all exhibit properties that cannot persist for billions of years.

The Nature article is free to view (though Hebert doesn’t link to it), and is a good read. You’ll certainly find much more detailed and nuanced information there than what Hebert provides. Continue reading
