New research strengthens hopes that, in the coming years, NASA will actually manage to find extraterrestrial life on the living moon Europa.
It has long been suspected that comets are one of a kind “lifestyle” carrier of the first organic molecules “seedling” for the Earth. Today, a study from the University of Texas, the California Institute of Technology and Williams College (United States) highlights the “form” Likewise, it could have landed on Europa, or even on Enceladus or Titan.
Beneath the icy surface of Jupiter’s moon lies a potential world of life

Europe is one of Jupiter’s four largest moons, while Enceladus and Titan are two of Saturn’s moons. All of these celestial bodies have revealed evidence suggesting that they have Earth-like conditions suitable for life in the subterranean ocean beneath the icy crust.
According to Scientific alert, These worlds are much further from the Sun than Earth and are located outside “living area” – is the area where celestial bodies are located “Take a shower” at a temperature just sufficient to maintain the water in a liquid state.
But the massive amount of data NASA has brought back from the moons of Jupiter and Saturn shows that their structure includes a underground ocean kept warm by the large outer ice shell and the same hydrothermal system at the bottom of Earth’s ocean – more precisely, similar to the hydrothermal systems of Antarctica and Hawaii.
Many land creatures have been found in dark waters similar to those of underground oceans, evolving in unique ways to adapt.
The missing piece to confirm that Europa or similar celestial bodies have life is an oxidant. They exist, but are limited to the surface, created by the impact of surface materials with solar radiation.
In the new study, the authors point out that comets not only bring life, but also help deliver necessary oxidants to subsurface oceans, as collisions temporarily melt surface ice. It is clear that the ice shells of these worlds bear traces of collisions.
Examine whether these effects are sufficient to trigger the process “sow the seeds of life” Whether or not this was true, the authors ran a mathematical simulation of Europa and determined that this was the most likely way the planet would respond to the impact of the impacts. Upon impact, 40% of the meltwater will mix with the ocean.
Thus, Europe has brought together all the conditions to give birth to life like Earth. Perhaps the last thing we should be thinking about is waiting for NASA’s Europa Clipper, under construction, which will send a robotic probe into the ice shell to search for signs of life.
