Europa's Ocean Floor May Lack Conditions for Life
Scientists studied Jupiter's moon Europa, which has a big ocean under its icy surface.
They wanted to see if this ocean could support life.
Their research suggests that the ocean floor is too strong for tectonic and volcanic activity, which on Earth helps create conditions for life.
Without these activities, it's harder for life to exist.
However, Europa still has liquid water, organic chemicals, and energy from Jupiter's tidal forces, which are important for life.
NASA's Europa Clipper mission, launched in 2024, will fly by Europa in 2031 to learn more about its conditions.
The scientists hope to be wrong and find that Europa could support life after all.
Europa's ocean floor is likely too strong for tectonic and volcanic activity, which are key for life on Earth.
The study considered Europa's size, rocky core, and Jupiter's gravitational forces.
Europa's ocean may contain double the water present in Earth's oceans.
NASA's Europa Clipper mission, launched in 2024, will conduct flybys starting in 2031 to examine Europa's conditions.
Europa possesses liquid water, organic chemistry, and energy from tidal heating, which are critical for supporting life.

“The effect of this tidal heating drops off quickly with distance, so although there's enough tidal heating to keep Europa's ocean from freezing solid, according to our calculations at least there's not nearly enough to tectonically deform the ocean floor. So, in short, there probably isn't the kind of thing happening on Io taking place deep within Europa.”

“Europa's subsurface ocean satisfies the first requirement. We've identified organic chemicals on this moon's exterior icy shell, and there may very well be such chemicals inside the ocean. So that's the second requirement. And Europa's particular orbit means that Jupiter drives tidal heating within Europa - requirement three.”

“Based on our findings, the seafloor would probably not contain major tectonic landforms, such as long ridges or deep troughs. There would likely not be any underwater volcanoes or seamounts, and we would not have any hydrothermal activity such as black smokers. Having said that, I hope I will stand corrected one day.”

“While geology operates similarly across the solar system, every planetary body that we have explored has been found to have some unique process to them. Given what we know about Europa, it is still the best place to look for extraterrestrial life.”
