Two new studies published in journals suggest the possibility that extraterrestrial life exists on Titan , a moon of Saturn.
The first magazine published in the online edition of Icarus, explains how hydrogen (gas abundant in the atmosphere of the star), disappears when it reaches the surface, so experts believe that some kind of living creature it would absorb, the agency reported today Prensa Latina.
For its part, the NASA Astrobiologist, Chris McKay, said in the Journal of Geophysical Research, that "something is consuming the hydrogen of Titan."
the same way that earthlings absorb oxygen, a way of life consume hydrogen on Titan, said the specialist.
"If confirmed, it will be doubly exciting as it would be a new way of life, independent of water based on Earth," said the scientist.
This planetary scientist at Ames Research Center (NASA) had responded to an interview in 2006: "I think one of the key goals for astrobiology should be the search for life on other planets and in particular the search for a second genesis. "
McKay is working "in the return to the moon with both the Lunar Precursor and Robotic Program, as the Constellation. As co-investigator on the Phoenix Lander and Mars Science Laboratory, is heavily involved in future Mars exploration, "according to the website Planets.
Also, Darrell Strobel, Johns Hopkins University in Baltimore, Maryland, who studies the upper atmosphere of Saturn and Titan emphasized that molecular hydrogen is "chemically very inert in atmosphere very light and very buoyant. " Should "float" into the upper atmosphere and escape, he said.
The studies are based on information obtained from the Cassini spacecraft a cooperative project of NASA, the European Space Agency and the Italian Space Agency, says the report PL.
