Rosaly Lopes has a new blog post on the Planetary Society blog on the mysteries still surrounding Everyone's Favorite Moon (and if it isn't your favorite moon, then may a giant, falling chunk of komatiite greet you ). She aludes to the upcoming observations by New Horizons to study surface changes and volcanic activity on Io, and to an upcoming book, on Io. The book, Io After Galileo, is currently on Amazon, but rest assured, it will be available until early 2007. here is a link to the book's Amazon.com page: http://www.amazon.com/Galileo-Springer-Pra...TF8&s=books -------------------- &@^^!% Jim!

I worked on one of the approach sequences taken by Voyager 1 on March 4, 1979. I believe that these series of images was the one where Linda Moribito noticed the faint eruptive plume from Pele and discovered Io's volcanic activity.
Full-size here I got a slightly better S/N ratio on the images because there were three clear filter images, and two images through each of the filter sets. I used the OGV combination. I've boosted the brightness and contrast of the space around Io a little to make the plume a little more obvious. It's striking how much brighter Pele's plume is at UV and blue wavelengths. Is that more from the sulfur content, or is there a psuedo-auroral emission from the ionizing radiation? |

II believe that these series of images was the one where Linda Moribito noticed the faint eruptive plume from Pele and discovered Io's volcanic activity. Io's activity was detected in an optical navigation long exposure image taken after the flyby (and thus showing the nightside of Io) |
