An interesting discovery has been made about Saturn’s moon Enceladus. According to this, extraterrestrial life could exist in the salty oceans beneath the moon’s icy surface. In fact, a new study has found methane, indicating the presence of microorganisms under the crust. The study also indicated that methane gas is behind a chemical process that we are not yet aware of.
Methane found in the data
Enceladus is Saturn’s sixth largest moon. It contains cool and clean ice, which makes it extremely reflective and cool. In 2014, NASA found evidence of water oceans here. Complex macromolecular organic compounds were also found in 2018. Cassini’s data was investigated in the new study. Along with methane, we also found hydrogen and carbon dioxide.
Saturn’s Enceladus moon oceans also have Earth-like waves, scientist claims
With this, scientists have shown the possibility that there were Earth-like hydrothermal vents in the ocean floor here. Microorganisms that live on hydrogen and carbon dioxide near hydrothermal vents on Earth produce methane. The research team prepared a model and saw what could be the reason behind the methane. The results of these models were matched with data from Cassini.
We can also see that what Cassini found could indicate a suitable environment for life, said study co-principal investigator Regis Ferrier. Moreover, if methane is produced on the ocean surface in Enceladus, we can also know its quantity.
Why are scientists wasting money on Mars, the Earth in crisis?
