Tonight from Boston

Tonight in Boston, United States, the sun sets at 20:22 local time and astronomical darkness — when even the faintest stars become visible — arrives at 22:35. The moon is in waning crescent phase, 6% illuminated. One major planet is above the horizon as night falls. Sunrise comes at 05:06.

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.
