This ability to generate heat in a subsurface ocean increases the chance of life on bodies like Europa and Based on their experience with the ancient surfaces of the Moon, Mars, and Mercury, scientists expected to see numerous Io's colorful appearance is the result of materials deposited by its extensive volcanism, including Compositional mapping and Io's high density suggest that Io contains little to no Io's surface is dotted with volcanic depressions known as Lava flows represent another major volcanic terrain on Io. Scientists have discovered that the yellow color seen on the surface of Jupiter's moon Europa is actually sodium chloride, a compound known on Earth as table salt. Io takes 1.77 Earth-days to orbit Jupiter. Jupiter's rocky moon Io is the most volcanically active world in the solar system, with hundreds of volcanoes, some erupting lava fountains dozens of miles (or kilometers) high. The Next Full Moon is the Strawberry Moon, Mead Moon, Honey Moon, Vat Purnima, Poson Poya, and the LRO Moon.

And the polar diameter of the Moon is 3,471.94 km. It is a slight ellipsoid in shape, with its longest axis directed toward Jupiter. Europa Clipper will explore Jupiter's icy moon in-depth during multiple flybys, studying whether Europa could harbor conditions suitable for life. This site is maintained by the Planetary Science Communications team at The first [moon] is called by me Io... Io, Europa, the boy Ganymede, and Callisto greatly pleased lustful Jupiter.Marius's names were not widely adopted until centuries later (mid-20th century).The customary English pronunciation of the name is Features on Io are named after characters and places from the Io myth, as well as deities of fire, volcanoes, the Sun, and thunder from various myths, and characters and places from For the next two and a half centuries, Io remained an unresolved, 5th-magnitude point of light in astronomers' telescopes.
Magma erupts onto the surface from vents on the floor of paterae or on the plains from fissures, producing inflated, compound lava flows similar to those seen at Io has 100 to 150 mountains. These particles originate in Io's upper atmosphere and are excited by collisions with ions in the Io orbits within a belt of intense radiation known as the Io plasma torus. Psyche, the NASA mission to explore a metal-rock asteroid of the same name, recently passed a crucial milestone.
This new Hubble Space Telescope view of Jupiter, taken on June 27, 2019, reveals the giant planet's trademark Great Red Spot. Introduction Jupiter's moon Io is the most volcanically active world in the Solar System, with hundreds of volcanoes, some erupting lava fountains dozens of miles (or kilometers) high. (2007) Outside astronomy, "Ionian" would likely be misunderstood as referring to With 3 680 km in diameters, Io seems tiny when she walks past the enormous globe of Jupiter the diameter of which is 143 000 km. Instead, most Ionian mountains form as the result of compressive stresses on the base of the lithosphere, which uplift and often tilt chunks of Io's crust through Mountains on Io (generally, structures rising above the surrounding plains) have a variety of morphologies. Io even has lakes of molten silicate lava on its surface.Io’s very thin atmosphere is primarily sulfur dioxide, which on Earth is sometimes used to preserve dried food.Io has no known moons of its own, but it is possible for moons to have moons.Io has no known rings, but it does create a gaseous torus of material along its orbit around Jupiter.Io almost certainly could not support life as we know it. Io is tidally locked, so the same side always faces Jupiter. Director, NASA Planetary Science Division:

NASA has selected four Discovery Program investigations to develop concept studies for new missions. Io is subjected to a double effect of tide which stretches its surface and its internal layers everywhere. The next full Moon will be early Saturday morning, September 14, 2019.
