Tonight from Boston

Tonight in Boston, United States, the sun sets at 19:19 local time and astronomical darkness — when even the faintest stars become visible — arrives at 20:59. The moon is in waning gibbous phase, 85% illuminated. 4 major planets are above the horizon as night falls. Sunrise comes at 06:09.

At mid-latitudes, night length varies substantially with season; summer offers shorter darkness, winter the longest. Polaris sits roughly at this latitude above the northern horizon, making it a permanent compass for navigation. The Big Dipper, Cassiopeia, and the northern circumpolar stars never set.
