A false color version of the mosaic has been created to enhance the contrast of the color variations. This causes Jupiter’s strong gravity to push and pull the small moon, producing immense heat inside Io and creating molten lava below its surface. Researchers have mapped material on the backside of Jupiters moon Europa, revealing that sulfur detected on its surface likely came from Io, a large and volcanically active Jovian moon. Most of Ios surface has pastel colors, punctuated by black, brown, green, orange, and red units near the active volcanic centers. The explanation was in fact very simple, Io's orbit around Jupiter is extremely elliptical, meaning that sometimes it's close to the giant planet and other times it's further away. Scientists initially scratched their heads and wondered how a small moon in one of the coldest parts of the solar system could be generating so much heat. The sulfur deposits from the eruptions also made the small moon strikingly colorful. One moon in particular stood out, Io, scientists were amazed to find out that it was in fact geologically active with volcanoes constantly erupting on its surface. It is very unlikely that life exists on Io.The spectacular surface of Io with volcanic plumeĪs Voyager 1 and 2 approached the Jupiter system in the late 1970's NASA scientists fully expected the craft to discover that its moons would be cold, dead and not particularly interesting, instead what they found was quite astonishing. But it would be far too poisonous for people to breathe. All the gas released from the volcanoes has created a thin atmosphere around Io. The plumes can reach a height of up to 500 km (310 miles) above the moon's surface. Some of these them are taller than Earth's Mount Everest. Io's surface is also dotted with more than 100 mountains. The Moon’s regolith is made up of approximately 45. When the Galileo spacecraft passed the moon it was able to take images of this activity. Meanwhile, the materials on the Moon’s surface is basically regolith in its original, untouched form. There are huge numbers of lava flows across the surface. Its surface is covered with hundreds of volcanoes. It is the hottest moon in the solar system, recording up to 2,600F around its 400 volcanoes, hotter. Io is the most active object in the Solar System. Io is one of the four Galilean moons of planet Jupiter. 26, 2000 This mosaic of images acquired by NASA's Galileo spacecraft on February 22, 2000, shows the highest resolution view ever obtained of the surface of Jupiter's volcanic moon Io, 5 to 6 meters (16 to 20 feet) per picture element. It is thought that this is why the moon is so active.

Io is named after a maiden who was loved by Zeus. It is just slightly larger than Earths moon. Some of the lava geysers erupt into heights of dozens of miles, or. The Maiden Io, eye-oh or eey-oh, is the fifth of Jupiters moons and the third largest. D) the Moon’s is similar to Earth’s crust, while Mercury’s is similar to the entire Earth. C) that density increases as we go outward from the Sun. That is where the similarities stop, however, as Io is extremely active geologically. B) similar in surface appearance, they are also similar in density. Io is the first of the Galilean moons, with a gravitational acceleration of 1.8 m/s 2 at its surface and a diameter of 3,642 kilometers, it is slightly larger than our moon. Density similar to Moon Tidal forces keep it geologically active. Comparing the densities of the Moon and Mercury, we find: A) the Moon is slightly denser than Mercury. Tidal Heating of Jupiter’s Galilean Moons Fig. Hint: appearance of surfaces of earth & moon. The changes in gravity pull at the moons surface. Io's surface, on the contrary, is covered in lakes of lava spouting from hundreds of volcanoes scattered on the moon's surface. Answer: Callisto(D) BB BB AA AAAAA B D Which moon has the oldest surface Do not look in your the pictures & deduce the answer. When it is close to Jupiter it feels a much stronger gravitational pull from the planet. This large change in distance has an effect on the moon. Sometimes the moon is very close to Jupiter and sometimes it much further away. This means that it always shows the same side to Jupiter. This means it makes an orbit of Jupiter in the same time it takes to rotate once. Just like Earth's Moon, Io is tidally locked to its planet.

It is a bit larger than the Earth's Moon.
