This is a montage of New Horizons images of Jupiter and its volcanic moon Io, taken during the spacecraft’s Jupiter flyby in early 2007. The Jupiter image is an infrared color composite taken by the spacecraft’s near-infrared imaging spectrometer which is why prominent bluish-white oval is actually the Great Red Spot.

The image shows a major eruption in progress on Io’s night side, at the northern volcano Tvashtar. Incandescent lava glows red beneath a 330-kilometer high volcanic plume, whose uppermost portions are illuminated by sunlight. The plume appears blue due to scattering of light by small particles in the plume. This montage appears on the cover of the Oct. 12, 2007 issue of Science magazine.

Why do the pictures come out square when the lens is round??

What a magnificent photo. To think this is 'real' is amazing to me! The colours, wow. Thank you so much for the explanation and for sharing this. I am finally getting where I can enjoy these lovelies!! Verena

Ouch! Amazing! Do you know what is the blue area at the right of Io?
First terrian colony? ;-)

I guess if Io is going to have eruptions, that scotches the theory that it functions as an Alien Way Station through this solar system! Seriously, this is an impressive, beautiful photograph...and thanks!

Pierre - the blue cloud is light being scattered through particles in the volcanic plume :-)

Arf! The "first colony" idea was a little more romantic... :-D

Phil;

This is a real beauty of a combo of space imagery, but Io looks pretty quiet in this shot. "Life" on this satellite would be a horror show: maps of Io go out of date within 6 months because the tremendous gravitational pull from a gas giant like Jupiter kneads this small satellite like a ball of dough, causing landforms to rise and fall as much as 330 feet in one revolution around the giant -- this kneading also keeps volcanic eruptions a constant, with pools of lava forming anywhere, filling the air with sulfur dioxide -- Jupiter's magnetic lines of force turn's Io into a huge electric generator, developing hundreds of thousands of volts and millions of amperes -- and the rotation of Jupiter literally peels tons of surface material off every second, filling the atmosphere with a thin ionized cloud full of radiation. When private travel companies finally (far in the future) offer vacations in the solar system, Io would be the least likely destination. (I left part of this information as a comment on a submission years ago but, as the heavenly bodies in our solar system are wont to do, things seldom change for them, unless, of course, a comet hits Jupiter [Shoemaker-Levy 9 in 1994] or the International Astronomical Union decides a planet isn't a planet [Pluto in 2006]). However, a trip to Io might make for a good movie, though.

If you've ever wanted to make a difference but found it hard to believe that one person could... check out the Kiva Team Caedes discussion thread and discover that anything is possible.
