Summary

Story summary

The study links the electric charge on interstellar gas clouds near the Sun to Epsilon Canis Majoris and Beta Canis Majoris.
It finds these stars significantly ionized local interstellar clouds, with 20% of hydrogen and 40% of helium ionized.
The study notes these stars were once closer to Earth.
The study, published in The Astrophysical Journal, identifies other radiation sources but concludes these two stars had the most significant impact.
