Kepler (the telescope, not the long-dead astronomer) just found the first multi-planet system that orbits a multi-star system. Now would be the appropriate time to invoke the Tatooine references.
This reminds us not only are there just a ton of “habitable zone” planets, but that they also orbit multiple types of star systems. You name a star system, we can probably put a planet around it.
Think about this: As habitable zone planets become more and more numerous, what will we use as a more useful indicator of whether they could harbor life? Because just being in the right place is not enough.
