NASA reveals the dwarf planet Ceres had a hidden ‘energy source’ that may have sparked alien life
The new NASA research suggests that Ceron – The dwarf planet closest to the earth – may have once had an old “source of power” which could have triggered the evolution of extraterrestrial life forms in the hidden ocean of the little world.
CERES is the largest object of the main asteroid belt in the solar system, which is located between the orbits of March And Jupiter. The weekend is around 600 miles (950 kilometers) wide, about a quarter the moondiameter, which means that it is not large enough to be considered a planet. But it is large enough to be considered a “dwarf planet” as Plutowhich lost its full planetary status in 2006.
There are five official dwarf planets In our cosmic district, others were waiting to be properly recognized by the international astronomical union, and many other discoveries expected in the coming decades. However, Ceres is the only one located in the inner solar system. The rest of the dwarf planets, which include Haumea, Makemake and Eris, are located far beyond the orbit of Neptune.
In recent years, scientists have learned a lot about Céres Thank you to the Dawn probe of NASA, which visited the object between 2014 and 2018. One of the most intriguing discoveries of the Dawn mission is that the giant Space Rock is probably a world of water: The traces of water and salted minerals on the ice surface of the dwarf planet suggest that a large brine of brine is trapped from kilometers below. Other studies have suggested that this underground ocean could also contain organic carbon, which is a key element of all life on earth.
However, so far, scientists thought it was unlikely that life appeared on Ceres because the dwarf planet has no energy source capable of launching life.
But in a new study, published on August 20 in the journal Scientific advancesThe researchers revealed that this was not always the case.

The study team has created IT models based on data collected by Dawn’s mission to simulate how the nucleus of the rocky body has changed over time. This revealed that the entrails of the dwarf planet probably emitted large amounts of energy in the form of heat – which raises that tiny extraterrestrial microbes could have appeared in the hidden ocean of ceres.
This could also have “major implications” for the potential to find life in other parts of the solar system, the main author of the study Samuel CourvilleA planetary scientist from the Arizona State University and a former trainee with the NASA laboratory propulsion, said in a NASA declaration.
Researchers think that the core of Ceres has issued significant quantities of heat from the progressive disintegration of radioactive isotopes. The team estimates that this heating lasted between 0.5 and 2 billion years after the creation of the giant rock, which was probably shortly after the rest of the solar system, around 4.6 billion years ago. At its warmest, the nucleus has probably reached around 530 degrees Fahrenheit (280 degrees Celsius), the researchers wrote.
This is not the first time that scientists have offered that Ceres had a radioactive nucleus. However, it is the best evidence to date that it has generated enough heat to potentially support life.
In addition to heating the underground ocean of the dwarf planet at a habitable temperature, the radiation could also have caused hot water jets and rich in minerals to browse the soil of the ocean, similar to hydrothermal ventilation systems on earth which support various microbial communities in the dark deep depths of our oceans.
“On earth, when hot water in the deep basement mixes with the ocean, the result is often a buffet for microbes – a chemical energy party,” said Courville.
Astrobiologists have proposed that similar systems can bear extraterrestrial life on other water worlds in the solar system, including SaturnThe moons of Enceladus and Titan, as well as the moons of Jupiter Europa and ganymede.
However, since the radioactive core of Ceres went dead about 2.5 billion years ago, any foreign microbe would probably have disappeared from the cold, which means that there is practically no chance that the dwarf planet supports life today, the researchers said.
