Grab a Flashlight, Cuz it's gonna get Dark

Okay, here's what happens in Isaac Asimov's "Nightfall". The final sun that the planet is orbiting around, Beta I believe, is going into an eclipse. This had been accounted for and scientists are at the ready for documentation at the same time, the Cultists, as they are called, are doing everything they can to stop the scientists because they believe that if they do this, they'll get taken to heaven I guess. To them, the eclipse is the rapture I think. Anyways, the scientists are getting ready to document the eclipse and have already taken the precaution if the psychologist turns out to be right. The psychologist, Sheerin, says that man will be driven insane by the lack of light and burn the city to the ground in an attempt to attain light. The scientists put their families and anyone that's important into a heavily fortified bunker for protection. The scientists, psychologist, and journalist are attacked by a single cultist trying to stop their operation. The story ends ambiguously with the sun going into its eclipse and the city residents coming towards them in the form of a mob rallied by the Cultists. Not a bad story overall, it just took some time getting into, mostly because it was in the form of a two column page which was hard for me to read.
