This morning on StarDate, we discovered that, over the years, comets have gotten some seriously bad press.
In fact, in 1910, folks were so concerned about the gases they feared were emitted by the tail of Halley's Comet, they were buying up pills alleged to combat the toxins (Apparently for those too poor to afford the rental of a "submarine boat").
