Europa is losing only about 12 kg of oxygen per second, much less than previously estimated.
The oxygen forms a tenuous atmosphere around Europa.
Some of the oxygen may seep through cracks in the surface and reach subsurface lakes.
This process enriches the lakes with oxygen and has implications for the potential for life on Europa.
These findings were made possible by observations from NASA's Juno spacecraft.
