Researchers have unraveled another mystery of the planet Ceres






















Researchers in the United States have been causing disappearance of craters on Ceres, a dwarf planet in the asteroid belt in our solar system.

The new findings suggest that the disappearance of craters could be produced over a hundred million years due to the frozen surface of the planet and geothermal activity. ,, We concluded that a significant number of craters on Ceres was obliterated beyond the recognized geological measurements over time, due to which the resulting film composition and evolution in the earth, '' said Simone Marchi, from Southwasr Research Institute of Colorado.

Before you find out possible reasons for the huge craters missing from Ceres, the team used a computer simulation to see how many formations should be.

They concluded that the planet formation should be at least 10-15 big craters with a diameter of at least 400 km. Thanks to NASA mission, researchers have found that there are only 16 craters on Ceres, but none has a diameter greater than 100 km.

The only similar formations are planitiae ,, '' (extended depressions) which were probably created following severe impacts with other objects. The team tried to discover how he managed to ,, violate Ceres' computer simulated data. They have developed several theories, though none is yet concrete.

One hypothesis is that Ceres formed long before the solar system to arise during the impacts with other objects were more rare. Over time, the dwarf planet's orbit placed it in the asteroid belt.

Another theory is reflected by geothermal activity, complemented by the frosted surface of the planet.

Lack is not the only huge craters geological mystery that researchers have recently solved

Earlier this month, researchers at NASA have discovered evidence suggesting that small bright spots discovered in the crater of Ceres come from an impact which scraped some of the planet's surface and left behind traces of sodium carbonate.

  Hello,

    I'm working on a theory for some time in trying to combine science with religion, looking for an answer to the question 
"What is the purpose of life in Creation?  Is it possible for life to be an unintended consequence of our Universe?

Finally due to space,science and exploration throughout the Universe we got everyone to agree with the fact that we are not the only planet with life.  My blog is full of interesting articles about Creation of the Universe with all his laws,  NASA's Missions,  History,   Science,  Physics, Health, Nature, Ancient origins and Culture.
