Tonight from London

Tonight in London, United Kingdom, the sun sets at 18:45 local time and astronomical darkness — when even the faintest stars become visible — arrives at 20:37. The moon is in full phase, 98% illuminated. 5 major planets are above the horizon as night falls. Sunrise comes at 06:57.

At this high latitude, winter nights are long and dark — among the best windows for deep-sky observation in the calendar. 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.
