Are we alone? This is one of the great recurring questions of mankind. Always the possibility that there is life beyond the limits of the Earth has fascinated human beings. Scientists from space agencies like NASA they are looking for an answer to that question.
When looking for life on another planet, the first thing scientists take into account is whether it meets certain habitat criteria: a close star and fundamental water, a valuable resource, but not so easy to find in other worlds.
And if instead of water, as we know it, we think of … methane?
Planetary scientist Amanda Hendrix, co-leader of the global ocean research program NASAtake a look at this world of our solar system, Titan, Moon of Saturncould take on "a strange extraterrestrial life based on methane."
"We have to find out if these oceans are habitable, and if so, if these oceans really live," he told British media, according to "Europe Press".
As you know, Titan is a world that has attracted the attention of scientists from NASA because there is an underground ocean as well as hydrocarbon lakes on its surface
"There may be some mad methane on Titan's surface," says Hendrix, who explains that it will not be "alien green-heads to swim around."
"There may be some simple forms of life in some of these ocean worlds in our external solar system," he said.
So far, Huygens' probe, which is part of Cassini's mission, is the only spacecraft that landed on Titan. However, this probe was not meant to "examine the ability" of Saturn's Moon.
However, there is currently a concept for the mission under investigation NASAThe Stressos mission, which will land on Titan and fly into its atmosphere. This mission can help to understand if finally mankind can find a response to the question of life in the universe.
DATA KEYS ABOUT TITAN, SATELLITE ON SATURN
It is the largest of Saturn's satellites and the second of the Solar System after Ganymede.
This is the only satellite in which clear evidence of surface fluid is found.
It was discovered on March 25, 1655 by Christian Huygens.
