Light pollution

Very high artificial light in central Boston: 122.4 nW/cm²/sr, brighter than 87% of the cities we cover.

Nearest dark area: about 77 km southeast of the city centre, about 38 km from Duxbury (42.075°, -70.208°). The ground there gives off almost no artificial light, and nor do its surroundings, so the night sky is far darker than in Boston.

Measured from space: NASA Black Marble VNP46A4 2025 annual composite (snow-free), NASA. This is light emitted upward from the ground at night, not a direct reading of sky brightness. A “dark area” here means a spot below 0.3 nW/cm²/sr whose surroundings, out to about 41 km, average below 0.5.
