  1. Congratulations on the fascinating findings. Forgive my astronomical ignorance, but I would really enjoy hearing the answers to several questions: The heliosphere protects us from cosmic radiation. Does this radiation emanate mainly from our galactic center? What would a heliosphere look like if the axis of rotation of a star is aligned pointing towards the galactic center? Would more cosmic rays then bombard the exoplanets of such a stars Would that make life less likely in such solar systems? Might this educate which solar systems to examine for life or for us to consider for colonization? Might The enhanced cosmic radiation change the chemistry of exoplanet atmospheres in ways that would be surprising, if we did not expect this additional cosmic radiation bombardment?
    You said that neutral hydrogen particles are important in shaping our heliosphere. I seem to remember that the neutral hydrogen after the Big Bang made the universe opaque and it was its ionization that made the universe transparent. Where are these vast quantities of neutral hydrogen coming from and why are they not ionized? I enjoyed hearing answers to any of the above. Thank you
