Tonight from Lisbon

Tonight in Lisbon, Portugal, the sun sets at 20:40 local time and astronomical darkness — when even the faintest stars become visible — arrives at 22:27. The moon is in waning crescent phase, 11% illuminated. No major planets are above the horizon at sunset. Sunrise comes at 06:24.

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.
