Io and Jupiter from Voyager 1
Here's an image I've been meaning to post for months, a new mosaic from Voyager 1 by Ted Stryk of Io crossing Jupiter's terminator as it neared closest approach.
Door 12 in the 2010 advent calendar
Time to open the twelfth door in the advent calendar. Where in the solar system is this trapezoidal mountain?
Field trip to Piton
Rosaly Lopes relates her time at a workshop in Piton.
Exposing Io's true colors
Thanks to its active volcanic activity and sulfur-rich surface, Io is one of the most colorful worlds yet seen in the Solar System, save the Earth of course
Volcanism across the solar system: Io
Three months ago, grandiosely, I announced that I was going to survey volcanism across the solar system, and I began the journey on Earth. Then I failed to follow up.
Volcanism across the solar system: Earth
Yesterday I asked for suggestions for topics to write about, and you readers seem to have volcanoes on your minds!
Pretty picture: Io, labeled
Jason Perry just posted this lovely labeled image of Io over at his blog, the Gish Bar Times.

400 Years of the Galilean Satellites
It was 400 years ago today that Galileo discovered smaller planets attending the planet Jupiter.
Planetary Society Advent Calendar for December 11: Io
This is a special post for all of my readers who are lighting the first candle on their menorot this evening.
Four hundred and fourteen years since Galileo
Galileo, the scientist, discovered the Galilean satellites of Jupiter four hundred years ago next month, while Galileo, the mission, arrived at Jupiter to study those moons in situ fourteen years ago Sunday.
Carnival of Space #126, plus more from Jupiter's moon Io
The 126th Space Carnival is live over at Jason Perry's always-excellent (if rather narrowly focused) Io blog The Gish Bar Times.
Aloha, Io
Taking a look at Jupiter's moon, Io, from Hawaii.
Frame a Pluto portrait
As New Horizons continues its journey (it's now approaching the orbital distance of Saturn, though it's very far from that planet in space), the mission is taking advantage of the recent experience with the Jupiter flyby to plan out the science operations for the Pluto-Charon encounter.
Tvashtar erupting -- the movie
I practically fell out of my chair when I saw this movie.
Io and Europa glimpsed by a retreating New Horizons
This image is beautiful for many reasons. It was captured by the MVIC imaging spectrometer, part of the Ralph instrument, on New Horizons, as it left the Jupiter system on March 2, 2007.
Io erupts, in color
The last one of New Horizons imaging instruments has finally checked in with a lovely image from the Jupiter flyby
Another amazing Io image from New Horizons
The Tvashtar eruption continues to amaze. All this time between Galileo and New Horizons, Io's volcanoes have probably continually produced spectacular eruptions like these.
New Horizons sees Io erupting!
There were two new pictures posted on the New Horizons Science Operations Center website this morning, of Io, and if you enhance the images a bit, there are two clear volcanic plumes visible on the limb -- Tvashtar and Prometheus are active!
New Horizons Jupiter Encounter Timeline
A year after its launch on January 19, 2006, New Horizons is fast closing in on Jupiter, the first target on its near decade-long journey. On February 28 the spacecraft will approach to within 2.3 million kilometers (1.4 million miles) of Jupiter before speeding along on to its way to the edge of the solar system.
