Pre-space scientists would have considered our colonization of Independence to be a remote possibility.  You see, Tau Aurigae is a G8 III, a yellow star whose surface is cooler than Earth’s sun.  But she is a giant star, one that reached the end of her previous life cycle long ago, expanded, and presumable burned her habitable planets away.  But when Independence Seven arrived in system, she found three planets orbiting the star.  One of them was a paradise.
