Europa may have less oxygen to fuel life in its seas than we thought

It is a hard for evolutionists, for “Jupiter’s moon Europa may be less ripe for life than we thought. Although it has an ocean of water beneath its icy shell, the frigid moon may be short of the oxygen necessary to sustain life as we know it.”

They just taught that Europa was ripe pr life. Now they are disappointed.  

“Oxygen is produced on Europa when radiation hits its surface and splits the water ice there into its constituent parts, hydrogen and oxygen. Models of that process have suggested the rate of oxygen production could be anywhere from 5 to over 1000 kilograms per second.

Jamey Szalay at Princeton University and his colleagues used data from the Juno spacecraft, which flew just 353 kilometres above Europa’s surface in 2022, to make a new estimate. They found oxygen is only being produced at a rate of about 12 kilograms per second on the surface – right at the low end of previous estimates.

“In some sense, the shell is like a lung for Europa. It’s continuously generating oxygen,” says Szalay. “That being said, we can’t speak to what happens after the oxygen is produced on the surface – it’s still a question how much of it could get into the ocean.”
