Titans Titan: on Saturn can live large organisms
American and German planetary scientists examined the possible forms of life that may exist on planets and moons with conditions other than zemnyh.Eto was made an example of extremophiles living on our planet. According to scientists, the living organisms, for example, on Mars instead of intracellular fluid may contain hydrogen peroxide. And being on Titan, as essential elements of life will have hydrocarbons.
«If you are considering a variety of options for what could be a life, you will not know how and what to look for," said Dirk Schulze-Makuch, one of the authors of the study
Of course, scientists do not claim that Mars or Titan is life - they only say that it "corresponds to the existence of physical and chemical laws, as well as biology».
So, in the world known bombardier beetles, which are used to scare away predators "shot" of a mixture of hydrogen peroxide and other compounds. Schulze-Makuch said that on Mars, this practice has led to the displacement of beetle 300 meters. In addition, hydrogen peroxide contained in the cells of Martian organisms that help them survive in the cold environment of the Red Planet, as it would act as antifreeze.
Martian organism as a whole may be similar to Earth, but the creatures biochemistry on Titan to be completely different. This is understandable, because the temperature of the surface of Saturn's moon is -180 ° C. Neither in its atmosphere, or on the same surface, in addition, almost no liquid water and carbon dioxide.
But on Titan has lakes of liquid methane and ethane. They could replace the water. On Saturn, moreover, possible hydrocarbon deposits and seasonal changes. So intracellular fluid organisms on Titan may contain hydrocarbon solutions.
And the eternal cold will lead to a very slow metabolism, and do their cells, according to scientists, will be extremely large. These organisms need to be long-lived, since the aging under such conditions should take place more slowly than that of the inhabitants of the earth.
