Tonight from Buenos Aires

Tonight in Buenos Aires, Argentina, the sun sets at 18:41 local time and astronomical darkness — when even the faintest stars become visible — arrives at 20:05. The moon is in new phase, 1% illuminated. 3 major planets are above the horizon as night falls. Sunrise comes at 06:58.

At mid-latitudes, night length varies substantially with season; summer offers shorter darkness, winter the longest. From the southern hemisphere, the Southern Cross dominates the sky and the Large and Small Magellanic Clouds — two satellite galaxies of the Milky Way visible only south of the equator — sit overhead in the winter months.
