SWIMMING AGAINST THE ANTI-INTELLECTUAL TIDE that these days governs too much of mediated public discourse is a modest little one-minute radio programlet called StarDate. It’s “the longest-running national radio science feature in the country,” according to the description on the StarDate website, and airs daily on more than 300 stations around the United States. A production of the University of Texas’ McDonald Observatory, each episode features something about astronomy (both historical and observable), planetary or space science, exploration, or even stellar mythology. (Everything stops in our house at 9:50 every morning so we can hear the broadcast on San Francisco’s KCBS.) You can catch it on the unstreamed local airwaves, or also listen online at http://stardate.org. Tune in, turn on and look up!
