  Io (moon) - Wikipedia, the free encyclopedia
Io (eye'-oe, IPA: /ˈaɪoʊ/, Greek Ῑώ) is the innermost of the four Galilean moons of Jupiter.
Although the name "Io" was suggested by Simon Marius soon after its discovery in 1610, this name and the names of the other Galilean satellites fell into disfavor for a considerable time, and were not revived in common use until the mid-20th century.
Io is most noteworthy for its volcanic nature; it is the most volcanically active body in the Solar System.

 Io - Wikipedia, the free encyclopedia
In Greek mythology, Io (IPA [ˈaɪoʊ] or [ˈiːoʊ]) was the daughter of Inachus, a river god.
Io (voievodal title particle) abbreviation of John (romanian: Ioan, latin:Ioannes), meaning "by the grace of God".
"Io" is the particle preceding the name of Romanian (Wallachian and Moldavian) voievods (rulers) during the middle ages.

 Io, Greek Mythology Link.
Io, who is one of the Three Main Ancestors, was turned into a cow after having been seduced by Zeus, and forced to wander over the whole world until she settled in Egypt.
Io is said to have been turned into a cow, either by Hera or Zeus, and then forced to wander over the whole world.
Io continued her wanderings through Scythia and Cimmeria (to the north of the Black Sea), met in Caucasus the bound Prometheus 1, and finally she came to Egypt.

 Io, Jupiter's Moon
Io acts as an electrical generator as it moves through Jupiter's magnetic field, developing 400,000 volts across its diameter and generating an electric current of 3 million amperes that flows along the magnetic field to the planet's ionosphere.
Based on density, surface composition analysis, and gravity data, Io appears to be a rocky silicate rich body that has a dense iron, iron sulfide core that extends halfway to the surface with a partially melted silicate rich mantle, and a thin rocky crust.
Plume 4 was not viewed on the edge of Io's disc by Voyager 2 and, therefore, it is not known whether it was still erupting.

 Io
Io was a maiden who was loved by Zeus (Jupiter) and transformed into a heifer in a vain attempt to hide her from the jealous Hera.
In contrast to most of the moons in the outer solar system, Io and Europa may be somewhat similar in bulk composition to the terrestrial planets, primarily composed of molten silicate rock.
Some of the hottest spots on Io may reach temperatures as high as 2000 K though the average is much lower, about 130 K. These hot spots are the principal mechanism by which Io loses its heat.

 Io, Jupiter's Moon
The Voyagers observed the eruption of nine volcanoes on Io altogether.

Auroras in Io's atmosphere is one likely result of the electron beams, they reported, and the two-way electron highway that the beams produce between Jupiter and Io must contribute to some of the auroras observed in Jupiter's atmosphere as well.
Io is immersed in the Io plasma torus, a gas of ions of O and S and electrons originating from the satellite itself and trapped around its orbit by Jupiter's magnetic field.

 Io
Io was an Argive princess and the daughter of Inachus, an ancient hero or river god of Argos.
Furthermore, and perhaps more importantly, she is the progenitor, thought removed by many generations, of Hercules, greatest of heroes, to whom Prometheus himself would owe his freedom.
Io, and the myth surrounding her, is important in several respects.

 Io
This wobbling stretches and bends Io by as much as 100 m (by comparison, the highest ocean tides on Earth only reach about 18 m) and generates heat in the same way that repeatedly flexing a rubber band causes it to warm up (see tidal heating).
Some of these hot spots on Io may reach temperatures as high as 2,000 K, compared with an average surface temperature of about 130 K, and are the principal means by which Io loses its heat.
Io's biggest volcano, Loki, is the most powerful volcano in the Solar System and consistently gives out more heat than all of Earth’s volcanoes put together.

 Jupiter's Moon Io   (Site not responding. Last check: 2007-10-21)
Io is one of 28 moons of Jupiter.
In addition, Io has tremendously high mountains, which are not volcanoes, and tectonic faults that give rise to the mountains and volcanoes, as well as split the mountains apart.
Finally, Io is surrounded by a plasma torus, an ionized cloud of alkali metals, chlorine, sulfur monoxide, sulfur dioxide, oxygen, and sulfur orginating from Io but a part of the Jovian magnetic field.

 Tidal Heating - Io: Jupiter’s Volcanic Moon
But Io is too small to have left over accretional heat, and radioactive decay could not generate the tremendous energy required to power all of the volcanic activity that exists on the moon.
Io, on the other hand, is a tiny moon which orbits very close to the giant planet.
Io's volcanic activity is caused by the powerful force of Jupiter's gravity, coupled with the gravitational pull of Io's neighboring moons--Europa, Callisto, and Ganymede.

 PSR Discoveries:Hot Idea: Hot, Mushy Io
If correct, Io gives us an opportunity to study processes that operate in huge, global magma systems, which scientists believe were important during the early history of the Moon and Earth, and possibly other planetary bodies as well.
Current estimates of the density of Io's interior range from 3.148 to 3.878 grams per cubic centimeter, though the currently favored value is 3.280, closer to the mushy than to the solid interior.
For example, Io is being heated continuously, so it does not allow formation of a crust by the floatation of low-density mineral grains, as happened on the Moon.

 CNN - Galileo returns closeups of volcanic Io - August 27, 1999
Io's surface facing away from Jupiter appeared mottled in earlier Galileo pictures, but now it looks even more blotchy, especially around Io's active volcanoes.
Io is the most volcanic object in our solar system, giving it a relatively smooth surface covered with molten material, scientists say.
With the upcoming Io passes this fall, scientists also hope to make up for a lost opportunity in December 1995 when the spacecraft passed directly by Io, within 900 km, but failed to collect data because of a broken tape recorder that has since been fixed.

 Making it stick.: The Io Programming Language
The ideas in Io are mostly inspired by Smalltalk (all values are objects), Self, NewtonScript and Act1 (prototype-based differential inheritance, actors and futures for concurrency), LISP (code is a runtime inspectable/modifiable tree) and Lua (small, embeddable).
Io has a syntax that does not always require an explicitly denoted receiver for a message.
For programmers looking to understand the "prototypes and delegation" approach to object-oriented programming (as opposed to "classes and inheritance"), then Io seems to be a simple way to dive in deep.
