Ceres is the largest object of the main asteroid belt and the only potential sea world in the inner solar system.
The global scan of an organic site on CERES using a deep neural network has revealed two new sites close to the well-known Ernutet crater. Image credit: Sarkar et al, Doi: 10.1029/2024AV001362.
“Ceres is the biggest object of the main asteroid belt, and the only potential sea world in the inner solar system,” said his colleague, Lanjansal Car, his colleagues, for the Max Prank Research Institute. Dr. said.
“It is a key to understanding the structure of the solar system as well as the formation and evolution of each planetary body.”
“The current position in the asteroid belt provides conditions in which water ice under the surface is potentially stored long-term.”
“The overall composition of Ceres has been known for many years, but the high space resolution data from NASA’s dawn mission has made individual evolution and small unique surface materials can be detected. “
“In these discoveries, the discovery of organic sites is an important site,” they added.
“In the previous research, three craters about Erunte, Inama Hari, and Ceres in Ulbara, including the deposits that could be detected in complicated organic compounds, were identified.”
In a new study, the author aimed to better understand the global distribution and geological context of all organic sites in CERES.
They use a deep neural network to scan the surface of the dwarf planet and identify an additional organic area that could have been overlooked in previous studies.
They discovered that only two newly identified reddish places actually contain organic materials.
In the organic parts of the previously known Ernte, Inama Hari, and Ulbara, it can be seen that organic materials are limited to the upper layer.
In addition, there may be no geological characteristics that suggest a living origin inside oral objects.
“Such organic molecules are actually rare in Ceres, and there is no signature for freezing plants,” said Dr. Sarkker.
“Most of the sediments can be found along the edge of the northern hemisphere of the dwarf planet or near a large Elntet crater.”
“Then there are only three places far away. The two patches were not known before.”
“If you look at the geological structure in the position of organic materials, you can further conclude.”
“Neither of the sediments had no evidence of the current or past volcanic activity or structural activity. There is no groove, gorge, volcanic dome, or ventilation, and there is no deeper impact crater nearby.” Dr. Martin Hoffman of the Max Plank Institute for Solar System Studies stated.
“Of course, the first assumption is that Ceres’s unique cliobolkanism transported organic materials from inside the body to the surface,” said Dr. Andreas Natles, at the Max Plank Research Institute for Solar System Research. Dr. Andreas Nathies also states.
“But our results are not so. There is no evidence of organic matter on the Cryvolcanic Activities.”
“If the organic compound is definitely detected, there is no evidence of deep or surface activity.”
