For a few months we had news of Philae who had resumed contact with his Rosetta. While landing has not performed as expected, Philae himself as a revealing more information since he is contacted Tchouri the comet.
The analysis of the most recent information that this robot was sent to earth to reveal to us that there seems to 4 organic molecules never before found on a comet have been detected by the small robot . These four molecules enter a chemical evolution chain that may eventually lead to the formation of basic building blocks of life.
Philaea discovered the existence of 16 different organic compounds including 4 special
In all, it was discovered the existence of 16 different organic compounds including 4 exceptional. This discovery proves revolutionary since many are precursors of life and have never yet been found on other comets. Clearly, this is a giant step in understanding the origin of life on earth as does the teacher understand Bibring. By way of illustration, there are methyl and acetone, precursors of sugars and amino acids that are essential for life.
The discovery of these organic molecules corroborates the theory that it is a comet or comets are the source of life on earth. We must understand that comets are believed to have remained intact since the formation of the solar system. These passing objects consist largely of ice. Tchouri therefore have organic debris trapped in ice for millennia.
The sun should make more active microorganisms
The discovery of organic compounds is conjecture that microorganisms adapting to cold exist on the comet. Images sent by Rosetta show that Tchouri has a variable area by geographic positions. In any case, the core is made of ice. But Willis professors and Wickramasinghe make us understand that the comet warms up it approaches the sun. This proximity to the star of our system should make microorganisms hidden in the ice more active.
Photos and discovered after seven months of hibernation
The pictures and Measures have been able to determine the position of Philae lying in a ditch, lying on its side with only two of the three legs touch the ground.
After arriving on November 12, she was able to run for 60 hours before sleep, for lack of sufficient sunlight to recharge its solar batteries. She woke up on June 13 after seven months of hibernation while the comet approached the sun. Since then, the robot barely sufficient to establish communication with Rosetta which is 200 kilometers far enough to avoid gas and dust jets.
In his eighth and last contact on July 9, Philae press longer transmitting data. But the quality of the communication has not enabled scientists to send commands to the robot to operate tools.
Philae will advance research on the origin of life
“We are convinced that Philae will make us significantly forward on the origin of life” on our planet and also on the fact whether or not it is common in the Universe, found Professor Bibring.
The four molecules detected on the comet entering a chain of chemical evolution can lead to the formation of basic building blocks of life, explains the scientist. This discovery was made shortly after the arrival of Philae turbulent November 12, 2014-after its separation from the orbiter Rosetta- by one of its ten instruments.
A total of sixteen compounds could be identified which fall into six classes of organic molecules including alcohols and amines. Among these molecules, the four never found so far on a comet are inter alia methyl, and acetone, important precursor molecules for life such as sugars and amino acids.
An overview of the chemical processes that occur in a cometary nucleus
But the presence of these complex compounds could not be identified with this first analysis, the researchers said. These observations provide insight into the chemical processes that occur in a comet nucleus and even already in the dust cloud which, collapsing, gave birth to the solar system there is 4.6 billion years, according to the astronomers .
Since comets have not undergone any change since the emergence of the solar system may be deduced from these observations, that these cometary organics were already agglomerated in several grains millimeters on as “Tchouri”. Previously thought that only small organic molecules were trapped in the ice of cometary nuclei.
It is such grain ending up in the oceans of the Earth and perhaps on other planets and moons elsewhere in the solar system, could encourage the emergence of life, say the authors of this work.
