Stargazing tonight in Cusco

High Andean air above Cusco thins haze and sharpens southern deep-sky targets. Altitude cold and thin oxygen matter as much as cloud decks for long sessions near the Sacred Valley.

Wet-season afternoons build storm towers that often clear for brilliant post-midnight skies.
