I’ve mentioned before that I used to direct a planetarium in Tennessee (which nobody is doing anything to reopen, as far as I can tell). One attitude I often had to battle was the idea that the planetarium shows were for kids. By extension, science topics like astronomy and planetary science are juvenile fascinations, things you outgrow as you mature. And yet: there was obviously a thirst for knowledge there among the adults accompanying children to the shows. I usually would follow up programs with opportunities for questions, and a lot of the grownups would ask far more basic questions than the kids. They needed to know this stuff, and without schools, the planetarium was the best source for answers.
The planetarium I ran was a small one, attached to a small college in a small city. It wasn’t a “destination” for tourists like the big museums, but as Maggie Koerth-Baker writes in Boing-Boing, science museums in general are failing to reach adults. Go read her article right now: she has examples both of good and bad things science centers are doing. I honestly think the situation is getting better over all, but let’s face it: there’s still room for improvement.
