According to the latest models, volcanic activity began 4.5 billion years ago and continues to this day in the depths of the moon of Jupiter, Europe. This phenomenon could also contribute to the emergence of life on an astronomical body with a huge ocean of salt water, dark on the outside but under a thick ice shield.
Do not miss this!
As prime minister, Ferenc Gyurcsany was still enthusiastic about China
Scientists have previously speculated that certain life forms may have emerged in Europe, and a study published in a recent issue of the journal Geophysical Research Letters confirms this hypothesis. Orego.
Our research found additional evidence that the underground ocean in Europe provides a favorable environment for the emergence of life.
Marie Bionkova, a fellow at Charles University in the Czech Republic, wrote in a statement on the NASA website.
“Europa may be one of the few celestial bodies that has maintained its volcanic activity for billions of years and has enormous quantities of water reserves and a sustainable source of energy.”
What is the depth?
An outside observer probably does not understand why experts’ imaginations stirred an icy world relatively far from the sun, and appears to be completely dead, with a surface temperature of barely -140 ° C. It might not be very useful to search for creatures on the surface of the moon, but the situation is very different when we look at the ocean hiding in the depths.
The life we know depends to a large extent on the food chain based on plant photosynthesis, but there are organisms that live even in the darkest areas; The latter are bacteria that live on land near volcanic chimneys in the deep sea and accumulate by chemical synthesis.
Other creatures can, of course, ingest the bacteria, creating stable food chains where there is no light at all.
