I Entered a City Where the Sun Does Not Rise for 40 Days

We travel from Bangkok through Moscow to Murmansk and Teriberka in northern Russia to experience the polar night, when the sun remains below the horizon for weeks. We explore the dark, snowy cities, visit the Arctic Ocean, learn about local life and the northern lights, and take a tour that includes husky sleds. We also discuss the Earth’s rotation, the seasons, and the evidence for its spherical shape.
