Hello everyone, First to preface I am not a scientist and have the heart of one (I purchased the heart from eBay... jk). Anyway I have a lingering question regarding Europa: Ok, I get the science about the tidal forces on Europa that flexes the rocky portion of Europa heating up the water and creating liquid middle and frozen outer layers. The theory is that there are thermal vents that may harbor life. But here is my question, from what I have "heard" the magnetic fields of Jupiter is so strong that probes that are sent there has to deal with radiation that could be lethal. So even though there is a liquid ocean, could the same magnetic field sterilize the life on Europa?
