Scientists from Germany’s Max Planck Institute have detected the cloud formation inside a Crater dwarf planet Ceres that may come from the sublimation of ice water, according A study published today in the journal Nature.
Andraes Natheus and his group of researchers used data from the probe Dawn (Dawn), which orbits Ceres from March to try to solve the mystery of the bright spots observed on the surface of the planet.
One of these reflections is the crater Occator , a hole 90 kilometers wide and 4 kilometers deep inside which appears and disappears a bright haze to a daily rate.
“Our detection of these clouds, in combination with recent observations observatory Herschel, who found steam in the vicinity of Ceres , suggests that there is water ice under Occator “he told Efe Natheus.
The group at the Max Planck has studied more than 130 bright areas has identified the ship NASA and concluded that the most of these reflexes may be due to the effect of sunlight on a surface hydrated magnesium sulfate.
“What we see they are salts in the solid state. Not ice, but contain links sulfate water “described Natheus, stressing that” under the surface there are probably saline water reserves. “
Los data it is sending the probe Dawn , the first human device that orbits the largest object in the asteroid belt between Mars and Jupiter have also served to scientists at the National Institute of Astrophysics of Italy (INAF) to delve into the details of the formation of Ceres.
According to their study, published Also today in Nature, minerals have been detected on the surface of the dwarf planet suggest that Ceres was born in the most remote regions of the solar system.
The American ship has enabled refining spectrometric observations that had been made so far and ground-based telescopes in orbit, so that scientists can now analyze more closely the composition of that body.
The new measurements suggest that there are phyllosilicates ammonia extended the surface of Ceres , suggesting that ammonia, which joined the planet as well as organic matter or ice, could react with other minerals from the body during training.
The ammonia ice is only stable at low temperatures outside the Plot system, so scientists believe that Ceres could be formed in these regions before being placed in the asteroid belt between Jupiter and Mars.
