Summary:
- Scientists have discovered a possible explanation for the chemical composition of Jupiter's moon Europa's subsurface ocean.
- The study suggests that the ocean may contain high levels of hydrogen peroxide, which could be produced by the interaction of Europa's ice shell and the moon's radiation-rich environment.
- This finding helps provide insights into the potential habitability of Europa's subsurface ocean, as hydrogen peroxide could serve as an energy source for any potential life forms.
