A thick atmosphere accomplishes roughly the same effect as a few feet of lead. A magnetic field could deflect incoming charged particles, but I'm not sure if a "shield" is feasible, due to any side effects that such a magnet might have.
- pyre 17y agoI was under the impression that the Earth's magnetic field was doing the majority of the work. IIRC, the reason that Mars has no atmosphere is probably due to lack of a (or just a weakened) magnetic field, causing solar winds to strip away the atmosphere.
