Recent study since Nose showed that Darknessthe largest dwarf planet asteroid belthe would have been in the past A durable source of chemical energyAble to create favorable conditions for Life.
Although in this remote world there is no evidence of organisms A laboratory of reactive movement (JPL) with NASA, support the hypothesis that Ceres gathered the main ingredients for livingIncreasing the search for life on the borders Terra.
Analysis that headed Sam Castville and published on August 20 in the magazine Science progresshe was counting on Thermal and chemical models which mimic the internal evolution of Cerero for billions.
The results indicate this, between them 2500 and 4000 million years agoSubsoil Ceres placed permanent nutrition Hot water and dissolved gases -What carbon dioxide and methane -expelled from Metamorphonated rocky core.
This internal energy formed Radioactive disintegration of itemswould support an underground environment that promotes Microbial lifeProvided it will arise, the team explained A laboratory of reactive movement NASA.
The relevance of this conclusion is enhanced because the presence of water and organic compounds in Ceres has already been confirmed The mission of dawn NASA, completed in 2018. These operations have shown that the brightest sections of the heavenly body are mostly formed vendorWhat are the remains fluid from the bowelsWhile investigations in 2020 have identified Big reservoir brine under the bark. Additional studies have discovered the necessary organic molecules for a lifetime, albeit isolated They are insufficient Maintain organisms.
New JPL NASA study includes The third key element For residence: A long source of chemical energy.
“On the ground, when hot water depth is mixed with the ocean, it usually becomes a banquet for germs, a true source of chemical energy. Therefore, it would be very important to determine whether the ocean will receive the Tserez dawn of the hydrothermal fluid.
Currently Currer shows a much colder and dry environment than in his past. The heat obtained from the radioactive decay no longer supports the water in the liquid state: most of the rest They became concentrated brine.
In addition, unlike the moon as Purify o Europereceiving the extra heat of the tidal forces of their master planets, Cerero is not enough of this mechanismthat limits its residence potential.
Period with the greatest potential for life in Ceres It was from 500 to 2000 million years after trainingWhen the rocky nucleus reached the maximum temperature and warm fluid mixed with groundwater.
This process, according to the JPL NASA models, created a chemically active environment for a long timeAlthough the dwarf planet is currently in a much more inert state.
The opening reviews the history of Ceres and expands the field of astrobiology in the solar system. Objects rich in water and similar size to Ceres – like other planets of dwarf and frost, without domestic heat sources formed by the tide – They could also survive the periods of residence in the pastcompleted the command A laboratory of reactive movement NASA.
