Using artificial intelligence to comb the data collected by the Fajr Fajr vehicle of NASA, scientists conducted a detailed examination of the dwarf planet to plan the areas rich in organic molecules to determine whether these “basic building blocks” that originated from the planet or were delivered by external sources.
Seris It has a great history. It is located in the asteroid belt between Jupiter and MarsIt was once classified as an asteroid. However, its size (CERES constitutes 25 % of the total mass of the asteroid belt) and the distinct characteristics are distinguished from its rocky neighbors, which prompted scientists to reclassify it as a dwarf planet in 2006. The volatile materials are expelled before Volcanic Instead of molten rocks.
It is this volcanic activity that prompted scientists previously assuming that organic molecules on the dwarf planet were created and transferred from the inner part of the dwarf planet, but this new male -powered study indicates a different interpretation. Of course, the first assumption [was] Andreas of the Max Planck Institute for Solar System Research (MPS) in Germany in Germany said: “The unique Cryovolconism from Siris has moved the organic matter from the inner part of the body to the surface,” said Andreas of the MAX Solar System Research Institute (MPS) in Germany in Germany. statement. “But our results show otherwise.”
Cres was explored by NASA dawn missionWhich arrived there in March 2015 and demanded the dwarf planet for three and a half years. During this time, the scientific camera of the spacecraft and a scale of the plane It drew its entire surface.
At that time, scholars Possible spots for organic materials have been identified By noticing that the amount of light reflected from certain areas on the surface of Ceres was higher in longer wavelengths. Often organic matter, especially those with complex molecules such as hydrocarbons, often reflects more light from the longest wavelengths due to their molecular structure, which affects how to absorb light and spread.
Based on their initial analysis, the researchers believed that the deposits that he identified can contain organic compounds with a chain -like structure, known as alifati hydrocarbons. However, their distant data cannot determine the exact types of molecules with any certainty.

Now, using artificial intelligence, scientists have analyzed the surface of the dwarf planet. While previous studies have identified organic compounds in specific areas, artificial intelligence allowed a systematic examination of the DAWN’s full data collection, and revealed previously ignored patterns.
Through reference spectral data with geological features, artificial intelligence helped the team confirm that organic materials were not actually linked Cryovolcanic activity sites. One of the study scholars, Ranjan Sarkar of the deputies, commented in the statement: “The sites of these organic molecules are actually rare for Cyris, and they are free from any signatures of Cryovolconic.”
These results help exclude the possibility that organic molecules originated from within the Ceres. On the contrary, where organic compounds were discovered reliably, there were no signs of deep or surface activity.
Martin Hoffman, also from the deputies, said: “In any of the deposits, we do not find evidence of the existence of a current or tectonic or tectonic activity: There are no trenches, cocaine, domes or volcanic openings.
The vast majority of sediments were along the large Ernutet hole in CERES in the northern hemisphere. There are only three at a greater distance. Two corrections were not known before.
“Unfortunately, Dawn cannot discover all kinds of organic compounds,” Natos said. However, the organic deposits that were discovered reliably with dawn are not established so far [from] Seris himself. “

One of the reasonable explanations proposed by the researchers is that the organic matter has been handed over to CERES with one or more effects Asteroids From the outside Asteroid A theory supported by computer simulation. This simulation shows that such asteroids often collide with Cres, but because they arise from the same public region, their relative speeds are low. As a result, the effects generate a little heat, allowing organic compounds to survive without destroying them.
This is important, because it indicates that the organic molecules could have been on asteroids and comets in the early solar system of their composition and have only reached the internal solar system at a later time, and may play a major role in the development of life here on Earth.
