In our Solar System, Jupiter is one of those planets which has more than one moon. All these moons are hotter than they should be, for being so far from the sun. The reason for their heating is the effect of Tidal Heating. Till now researchers believed that this effect was only due to the planet Jupiter, but recent research shows that Jupiter's moon Europa, Ganymede, Io, and Callisto have a major contribution to warming each other.
Tidal Heating is the gravitational effect due to which the stretch and squish created ult imately produces heat in the Moon. The reason for this is that the ice inside these moons is so melted that an ocean is formed under the ice, even in a rocky moon, it melts rocks and forms magma there.
In the study published in Geophysical Research Letters, it has been found that planet Jupiter is less responsible for generating this heat but rather the moon-moon interactions may be more responsible for the heating. The study's lead researcher Hamish Hay says that this is surprising because these moons are much smaller than the Jupiter.
It is important to understand the effect of these moons on each other, because it can provide important information about the formation and development of the system of moons. The planet Jupiter has 80 moons of which the largest four moons are Lo, Europa, Ganymede and Callisto.
Researchers say that for so long in the seas below the surface of the ice, coordination between internal heat and heat loss is necessary. This has been seen on many moons. At the same time, on a rocky moon "lo", which is closest to the planet Jupiter, there are many active Volcanoes. This is also the result of tidal heating. Researchers want to know the source of heat so that they can get information about their development and hability development.
Researchers say that Tidal Heating is related to Tidal Resonance process. When there is a push on an object and it is released, a situation of oscillating an object is created. If the process continues a kind of vibration produces. Pushing at the right time increases the effect. Same effect cause by the effect of the gravity of some celestial bodies, such as planet, moons and satellites. Which is called Tidal Resonance.
The natural frequency of the vibrations of the Jupiter's Moon depends on the depth of its Oceans. Earlier it was believed that Jupiter was responsible for most of the tidal heating associated with the liquid interiors of the moons. But this effect would have arisen only if the depth of these oceans was up to 300 meters, which is not. But for the effect of the Tidal Resonance of other moons, their oceans should be hundreds of kilometers deep, which is.
When the effect of Tidal Resonance due to the gravity of other moons matches the a moon's own frequency, the heat in that moon starts increasing. And sometimes even the ice or rock inside that moon melts inside. After all the analysis, it has been confirmed in research that Jupiter's moons are responsible itself for causing heat to each other in this way.
