For the mountain lovers, here's a graphic labeling all the mountains, except for the little guy northeast of Gish Bar Patera.

Thanks, VP! Io's mountain landforms are strangely more fascinating to me than the volcanoes, but I'm biased in favor of tall stuff.
Here's a link to Schenk and Hargitai's database project for anyone interested: Io Mountain Database Nice work on the colorized pic, Stu! edit: The lighting geometry on the Hi'iaka Montes looks very similar to that seen on Galileo's passes. -------------------- ...if you don't like my melody, i'll sing it in a major key, i'll sing it very happily. heavens! everybody's all aboard? let's take it back to that minor chord...

Here's another take on the changes at Masubi since Galileo. Comparison again is to the Galileo frame that volcanopele posted, flipping back and forth with the latest new LORRI frame. It looks like the current Masubi eruption is spewing primarily from what used to be that corner bend of Masubi Fluctus, with maybe some secondary plume(s) to the east.

You have to be kinda careful about colorizing high-phase Io images. Io's colors can change quite dramatically as you increase phase angle.
BTW, thanks for pointing out that the raw images are now up, including the shorter exposed images of Io. Here is the 4 msec exposure image with Shango Patera pointed out: -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

I'd say it's always pretty active. Maybe not huge volcanoes such as Pele or Tvashtar, but smaller ones, yes. And Io's not that small a moon either!

A "seven error game"
The image of the left comes from Celestia, I've desatrured it and darken the night side to have a good model comparison. The differences are very small... -------------------- |

The feature that ustrax circled is actually a cosmic ray hit; it's only present in the 20 msec exposure.

HERE BE DRAGONS…
Through your telescopes I am Merely a star, a spark of light that slides And glides ‘round proud Jupiter; One night here, the next night there, Sometimes with company, often alone On Jove’s left or right. One of four Fluttering fireflies flitting silently through The blush of the Red Spot’s glow. But dare to approach me, to brave Jupiter’s Cell-scything rays and you’ll crave The safety of Earth once more, for I am a world Where chemistry screams at the sky And tears at your eyes, with claws Of colour so sharp and so raw You’ll turn your face away and seek The comfort of Callisto’s cratered smile. For where my colder, older brother And sister moons glow shivering shades of blue And grey, my tortured face is painted hues Of fiery red; instead of frigid plains Of painfully pastel tones, my bones lie under Seeping fields of sores and blistering boils. A pox-infected moon am I, a leprous satellite That brings my smooth-skinned family shame. Yet, if they knew my secret, the mysteries I keep hidden from their disapproving View, they would feel envy, for the tangerine- And clementine-hued splashes on my Face are not mere volcanoes, as your Earthly scientists believe, but are great blooms And plumes of fyre, breathed out by beasts Which bathe beneath my Jupiter-racked crust. Maui, Marduk, Loki – dragons all, and with Volund and Pele prowl and crawl thru my sulphurous Churning seas; wings outstretched, tails sweeping To and fro below my scabby-encrusted skin, Swimming, spinning, gorging on my Bitter bile before breaking through to spew Their flaming breath out into space in great Gushes of furious light. What a sight! And what luck you had, sending one of your Nuts and bolts butterflies gliding past me Just as mighty Tvashtar roared, vomiting his Dragonfyre towards the stars, howling with Masubi and Prometheus in a choir of dragons Singing to the Great One’s swirling storms; What fortune to soar through this cloud of worlds On your way to the Belt, and Beyond… © Stuart Atkinson 2007 -------------------- |

"nuts and bolts butterflies gliding past me"...
Brilliant as usual, O Laureate....thank you! -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
