One study, in the journal Icarus, shows hydrogen gas flowing throughout the planet’s atmosphere, showing that alien forms could possibly breathe. Another paper, in the Journal of Geophysical Research, says there is no hydrogen on the surface of Titan. The hydrogen theory scientists believe the hydrogen may have been consumed by life. Huh? Like, they used it up?
According to NASA, "researchers expected sunlight interacting with chemicals in the atmosphere to produce acetylene gas. But the Cassini probe did not detect any such gas."
"If these signs do turn out to be a sign of life, it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth.”
Professor John Zarnecki, of the Open University, said “We believe the chemistry is there for life to form. It just needs heat and warmth to kick-start the process."
They warned, as these tricksy scientists always do, that there could be other explanations for their findings. However, "taken together, these studies indicate two important conditions necessary for methane-based life to exist."
