Just let you all know about a new blog I've started called The Gish Bar Times located at http://gishbar.blogspot.com/ . I intend to use the blog to cover Io-related news like new papers or abstracts, developments with the flagship mission selection process, newly processed images, volcano news, or pretty photos taken of Io and Jupiter. I hope you all enjoy!

Thanks again, Jason, for those great summaries of the work of Galileo and his contemporaries.
A question that interests me is when the Laplace resonance (the 4:2:1 ratio of the orbital periods of Ganymede, Europa, and Io) was first noticed and what people made of it at the time. Laplace explained the resonance much later, in the 1700s. You would think the resonance would have been noticed very early, given the great interest in the Galilean satellites at the time, especially their importance for navigation. You would also expect a lot of speculation on the meaning of the resonance once it was noticed. But I haven't heard any discussion of this. John |
