What is the structure of Io? What is Europa s main structure

Io is mostly made up of red-hot silicate rocks. Its surface is also very different from other stars in the solar system, which surprised scientists when they first came into contact with the data sent back by Voyager. They thought that the terrestrial bodies should be covered with large and small craters left by impacts, and then estimated the age of the planet's crust based on the "craters" left in the unit area.

But in reality, there are very few surface craters on Io, which are almost a handful. In this way, it looks very young on the surface.

Io's terrain is varied: craters thousands of meters deep, blazing sulfur lakes, unmistakably non-volcanic mountain ranges with hundreds of kilometers of viscous liquid, and some volcanic vents. The variety of colors of sulfur and its compounds gives the color of Io's surface a variety of colors.

The hottest temperature on Io's surface can reach 700 K, although its average temperature is only about 130 K. These hot spots are the main reason why Europa loses its heat. Unlike the other moons discovered by Galileo, Europa has almost no water.

This may be due to the fact that Jupiter was so hot at the beginning of the solar system's evolution that it vaporized all of Europa's more volatile material.

Europa (English pronunciation"yoo roh puh"), which was discovered by Galileo in 1610, is the sixth known moon of Jupiter, the fourth largest moon of Jupiter, and the second closest to Jupiter among the moons discovered by Galileo. Slightly smaller than Earth's moon, the Moon, with a diameter of 3,100 kilometers, Europa is the sixth largest moon and the fifteenth largest body in the solar system. Hubble observations revealed that Europa had a rarefied atmosphere containing oxygen.

Europa's main body is similar to that of terrestrial planets, i.e., it is mostly composed of silicate rocks.

Its surface is covered with water, presumably hundreds of kilometers thick (frozen hail ice crust at the top, and a liquid ocean underneath the ice crust), and magnetic data collected by the Galileo spacecraft, which orbited Jupiter between 1995 and 2003, suggests that Europa is capable of generating an induced magnetic field of its own under the influence of Jupiter's magnetic field, a discovery that suggests that there is likely a conductive layer similar to that of a saltwater ocean within its surface, and that Europa may also have a metallic iron core.

Europa is the fourth largest moon in the solar system. It has more than 400 active volcanoes on its surface. Volcanic eruptions cover much of Io's surface with sulfur, sulfur dioxide, and silicates, and Io's sulfur and its compounds have a variety of colors that give it its unique and varied appearance.

Io, or Io, is the closest of Jupiter's four Galilean moons, with a diameter of 3,642 kilometers, the fourth largest moon in the solar system. It takes its name from one of the lovers of Zeus, the king of the gods: Io, a priestess of Hera.

Calmede Carme (pronounced kar mee in English) is the fourteenth moon from Jupiter

The interior of Io is mentioned in Arthur C. C. Clarke's 2010: Odyssey Two (1984), which features observation of Io by the spacecraft Discovery, whose hull is covered in sulfur ejected from a volcano.

In the television series Babylon 5, Europa is one of its colonies.

In the manga Mobile Suit Pirate Gundam, the news that Europa (referred to as Io in the artwork) is the base of the Jupiter Empire is leaked to the Crusader Heralds, so the Crusader Heralds decide to strike Io.
