Why Stars Twinkle and Planets Do Not
There is a question that children ask and adults forget to. Why do stars twinkle? It is, on its surface, a simple thing. You look up, you see it: a star pulses, shivers, flickers like a candle flame behind old glass. The planet next to it, however, sits there fat and steady, smugly unperturbed. Same sky, same night, same pair of eyes. And yet one trembles while the other does not.
