Redefining habitable zone for advanced Terran animals

[stevebowers]

I'm quite keen on the use of Lagrange sunshields and magshields to protect planets in high-energy environments. A large semitransparent or relatively opaque shield or swarm placed between the star and the planet could absorb starlight and re-emit it at acceptable strengths and wavelengths, while also incorporating a magshield if necessary. One major problem would be damage and displacement by superflares or CMEs; but it seems likely that this sort of problem would be relatively minor compare to the effort required to place the shield in the first place.
