    Undergrad Supernova 7000 ly Away: Impact on Earth and Light Visibility

    Yes, I'm referring to Eta Carinae, I have seen many pictures about supernovas in several galaxys, and in each one of them the light of the supernova almost offuscate the entire host galaxy. our milky way has 100.000 ly of size from one side to the other, 7000 ly is almost "around the corner"...
