Mars is still full with many mysteries, but thanks to the work of scientists every day we will learn something new about this planet. Space information portal.com speak About the way NASA's employee reveals new information about the origin of the planet and its core.
The planets include different classes. On the surface where we are in – the bark is located on the top of the coating. And deeper, much deeper, an outer core of the solid and the core inside melting are hidden, with a rotation that creates the planet's magnetic field.
The planet scientists call this a distinction of this stratification – each class has its own features. Severe factors, especially iron and nickel, often fall into the core of the planets, while light silicate factors are closer to the surface. However, scientists have previously believed that to penetrate iron and nickel to such a depth, the inner layers of the planet must be hot, heated by the radioactive decay of aluminum-26 and, maybe iron-56.
The Earth is almost certainly formed in this way. But Mars is another story. The fire meteorites contain radioactive evidence that the planet's nucleus has not been formed billions of years, like earth, but only a few million years before the solar system was born. In other words, Mars forms much faster than the Earth, but the formation models are known for science that cannot repeat this result.
But recently, NASA's staff may have found an answer. 4.5-4.6 billion years ago, planets from the dust clouds and the air of the universe around the sun. The star's gravity has pulled heavy elements and minerals, including iron and nickel, inside the plate, while light materials, such as water and hydrogen, are still outside.
The place where Mars is formed is somewhere between these two parts. There is a lot of iron and nickel, but there is enough space for light elements. Scientists from the NASA laboratory realized that this could affect the nuclear formation of NASA and have conducted a number of high temperature experiments. They heat saturated stone samples with sulfate up to 1,020 degrees Celsius, hot enough to melt the sulfide, but not a silicate rock. After that, experts studied hot samples using a layered tanning to check if silicate was leaked through a solid variety.
Experience shows that they are actually leaked. And this means iron and molten nickel can pass through solid minerals and sooner or later, screaming into the planet's nucleus just a few million years before the radioactive decay melt it.
It is noteworthy that this nucleus model is applied to all major objects in the middle of the primeval disk, and not only with Mars. However, the finding scientists answered one of the questions about the origin of the planet, and also showed that the core of Mars could be rich in gray.
