The Making Of episode, one of my favorite hours of this excellent series, is repeated tonight at 7 p.m. ET. Then, at 8, comes a new installment: Life in the Freezer, including stunning looks far beneath the northern ice shelf, and even way, way above it: to the aurora borealis. And if these northern lights, shown in sped-up time-lapse photography, don’t amaze you, you just may be incapable of amazement.
