NASA scientists have found that cell-like compartments, which referred to as vesicles, could form the forerunner of living cells, in the lakes of Titan, the largest moon of Saturn.
These lakes and Titans seas are more filled with liquid hydrocarbons such as ethane and methane than water. And although we know that water is an integral part of life on earth, astrobiologists have theorized that Titans liquid hydrocarbons could enable the molecules that are needed for life, whether life is similar to that on earth or a completely different way of life.
This new research suggests that Vesikel could form on Titan, based on what we know about its atmosphere and chemistry. The formation of such compartments is an important step on the way to the development of “protocelles”.
“The existence of vesicles via Titan would show an increase in the order and complexity that are necessary for the origin of life,” said Conor Nixon from the Goddard Space Flight Center in NASA in an explanation.
“We look forward to these new ideas because they open up new directions in Titan research and change the way we are looking for Titan in the future.”
The way to life begins with bags
The process of producing vesicles begins with molecules called amphiphile, two natural molecules with water -loving (hydrophilic) and water -repellent (hydrophobic) end. Under certain conditions, these molecules can organize themselves to create vesicles.
On earth, when amphiphile water meet, they group together to form bullets that resemble the water -loving end to the outside like soap bubbles and protect the hydrophobic end.
If two layers of amphiphili are together, you can form a double layer ball with a cover of water that is trapped between the two molecules. A structure that resembles a living cell.
This process would be very different on Titan due to its surroundings, which differs radically from the earth.

Titan is not just the largest moon in the solar system; It is also the moon with the densest atmosphere. This is primarily due to the cool temperature of the titanium and the removal from the sun, which prevents its atmosphere from being withdrawn from the sun wind.
From 2004 to 2017, the Cassini spaceship was able to stare through this essential atmosphere to find out how the meteorological cycle of Titan has influenced its surface.
Although most Titan’s atmosphere are made of nitrogen, its clouds consist of methane, which undermines the surface and river channels when it falls as rain and fills its lakes and seas. When the methane is exposed to sunlight, it evaporates and rises again into the atmosphere and regenerates the clouds of the titanium.
The activity of methane through titanium atmosphere enables complex chemistry, especially when sunlight divides methane molecules and creates fragments that are recombinated as complex organic molecules.

This team theorizes that Vesikel could form on Titan if sea spray droplets are thrown into the atmosphere by methane rain drops on the surface of lakes and seas.
If Titan’s surfaces are coated with amphiphil layers, it is also the drops of sea. This means that if these written droplets fall back on the methane sea, they meet the Amphiphile lake layer and form a double-layer vesicle that includes the original droplet.
Over time, these vesicles could be distributed through the lakes and seas, interact and possibly lead to the creation of protocelles.
