Investigation Nose He discovered it In dwarf Ceres could be a deep and long source of chemical source that may have supported residential conditions in the pastAccording to NASA.
In depth
In this sense, this source of chemical energy comes from the types of molecules necessary for feeding certain microbial metabolisms. Although there is no evidence of the existence of microorganisms in CeresStay supports the theories that this planet, the largest body in the main asteroid zone between Mars and Jupiter.
However, this result does not mean that Cerer has placed life, but probably there are “food“Available when life appeared in Ceres, research published this week”Science progress‘.
In this sense, the scientific data of the mission ‘Dawn‘NASA, completed in 2018, showed that bright and reflection regions of Ceres were composed of Residual fluid salts that have been leaked from the bowels.
After the analysis conducted in 2020, showed that the source of this fluid was A huge reserve of pickle or salty water, under the surface. In addition, in another investigation, the dawn mission also revealed evidence that Cerer contains organic material in the form of carbon molecules, though necessary Insufficient on its own, for nourishment of microbial cells.
In the current study, the authors created thermal and chemical models that mimic the temperature and composition of the inside of Ceres over time. Thus, they found that about 2.5 billion years ago, the underground Terer could constantly supply hot water with dissolved gases that grew from the metamorfed rocks of the rock kernel. The heat came from the breakdownThe internal process, which is believed to be “common” in the solar system, they confirmed.

The chief author of the study, Sam Kuville, explained that “on the ground, when hot water depths are mixed with the ocean, as a result, there is usually a chemical energy holiday for germs.” So determine whether the ocean has received a curera inflow of hydrothermal fluid in the past “I might have important consequences“He said.
However, it is unlikely that Cerer, known today, is residential, because it is colder, with more ice and less water than in the past. Currently heat from radioactive disintegration in Curie “insufficient“To avoid freezing water, and the rest of the fluid became concentrated brine, NASA’s study emphasizes.
Thus, the investigation affects the fact that the period in which Curie was probably residential, made from 500 to 2000 million years after its formation (or from 2500 to 4000 million years ago) when its rocky core reached the maximum temperature. It was then that the warm fluid was introduced into the underground waters of the cherry.
Consider
The planet dwarf also also does not use the modern warming that arises and involvement in orbit on the great planet, as they do on the moon and Europe, the moon of Jupiter. ThereforeThe greatest potential of Ceres for gaining energy that allowed her life was already in the past.
This result also matters for objects rich in water from the external solar system because many other planets are frost and dwarfs similar to Cereer (about 940 kilometers in diameter) and that do not suffer significantly inner heating that belongs To the gravitational attraction of planets, they could also have a residence period in the past.
