Tonight from Lisbon

Tonight in Lisbon, Portugal, the sun sets at 21:03 local time and astronomical darkness — when even the faintest stars become visible — arrives at 23:01. The moon is in new phase, 3% illuminated. 7 major planets are above the horizon as night falls. Sunrise comes at 06:11.

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.
