Almost like the Sun. Why Jupiter is so beautiful

Почти как Солнце. Почему Юпитер так прекрасен

A gas giant with his companions like a little solar system.

Recently, scientists have discovered that Jupiter is not only the largest but also the oldest planet in the Solar system.

According to astronomers, the Solar system appeared about 4.5 billion years ago. The planets were formed during the rotation of the protoplanetary disk that surrounded the Sun.

The solid core of Jupiter was formed through one million years after the formation of the Solar system. Later it began to attract a substance that was a gas shell of Jupiter.

Jupiter can be called the most beautiful planet in intricate patterns on its surface are fascinating not worse than interstellar nebulae.

Mini solar system

Jupiter is a planet most similar to the Sun. It’s a giant ball of gas consisting mostly of hydrogen and helium, which did not have enough mass to ignite a thermonuclear reaction inside.

In addition, Jupiter with its many moons can be considered a model of the Solar system – almost a star and orbiting her planet satellites. It is of the greatest interest for scientists.

The number of satellites Jupiter has reached 69. Their sizes range from a few tens of kilometers to the large Galilean moons, the size of which is several thousand kilometers.

The largest planet in the Solar system has, in particular, the largest moon is Ganymede, which amount exceeds the mercury – the smallest planet in the solar system.

The Galilean satellites were discovered by Galileo Galilei in the 17th century. This is a great body already formed internal structure. The moons of Jupiter properties are significantly different from each other.

Large moons orbit the planet at a distance of from half a million to two million kilometers.

The inner satellite IO is the most active volcanic moon. The colors of this body suggests that the surface is constantly changing.

Satellites that are farther from the planet, covered by ice. This is Europa, Ganymede and Calisto. Recent discoveries have shown that these satellites may have a subsurface ocean.

New knowledge changed scientists ‘ ideas about what is called the habitability of the universe. Prior to these discoveries it was thought that Sarojini life is possible only on the surface of planets.

That is why Jupiter’s moons are the focus of modern science.

Europa’s ocean as pokazyvaem modeling, in contact with a rocky surface, so the emission of volcanic activity it gets, thus creating a primary “broth” for the origin of life.

The Satellite Europe

Ganymede is a different situation – his ocean sandwiched between ice layers. However, it is interesting because it is the only moons of the Solar system with a magnetic field.

The fourth of the Galilean moons – Callisto. Scientists call it a benchmark in the Solar system because it is the oldest satellite with the most ancient surface.

In fact, a test plate etched meteorite impact, since the formation of the Solar system, while on other bodies in the Solar system, it was already oiled, washed, changed geological processes.

The Satellite Callisto

Another aspect is that Callisto is completely differentiated body, i.e., inside still there is a complete separation of the heavy elements that usually fall down to the core elements such as iron.

These satellites, as well as the whole system is immersed in a huge magnetosphere of Jupiter.
