Under the surface of the largest moon of Jupiter, Ganymede, is a vast ocean of salt water. Probably there are more water than on Earth. That the US space agency NASA announced today
.
Water is important in the search for possibilities of extraterrestrial life.
The surface of Ganymede is composed of a thick layer of ice of about 150 kilometers. Among them would be the ocean. Which is believed to 100 kilometers deep. In comparison, the deepest point in the ocean on Earth is nearly 11 kilometers below the sea
Biggest Moon
. Ganymede is the largest moon in our solar system. It is larger than the planet Mercury and nearly 3.5 times as big as our moon. Ganymede is so large that it has its own magnetic field, like the sun and the planets. This magnetic field causes auroras on Ganymede like Earth.
The US-European Hubble Space Telescope has studied so-called auroras. “If you look at the auroras in a certain way, you learn something about the magnetic field. If you know the magnetic field, you know something about the interior of the moon, “says the German principal investigator Joachim Saur.
Scientists believe that there is water on Enceladus, one of Saturn’s moons. Titan, another moon of Saturn, is also an ocean. Not of water but of liquid methane and ethane. On Earth, gases, but on Titan, the liquid substances by the extreme cold
