Tonight’s sky
When it gets dark, what the moon’s doing, and which planets are up — for planning a night under the stars.

Darker nights (lower %) are best for galaxies and nebulae. Tap any night to see its darkness, moon, planets and ISS passes.
Waning crescent · 37% lit
A 37%-lit moon is up for some of the dark window — deep-sky objects still show, brightest targets best.

ISS passes (naked eye)
ISS pass times are unavailable right now — The ISS orbit data is out of date — check back later.
Sun & Moon path (altitude over 24h)
The shaded band is the genuinely-dark part of the night. A target is easy to observe when its curve is high (above ~30°) during that band; low on the horizon means haze and rooftops. Times are EEST (local).

Meteor showers are best on a moonless night away from town lights — use the moon panel above to judge. Eclipse and shower dates are worldwide; whether it’s above your horizon depends on your location and time.
Every time is shown in Kos’s own local clock, with daylight saving applied for the date. “—” means the event doesn’t occur (for example, some nights the moon doesn’t rise); “stays light” means the sky never reaches that stage (northern summer). ISS pass times use live orbital data and show only passes visible to the naked eye (bright enough, in a dark-enough sky). Planet visibility is judged during the genuinely-dark window, not by a daytime high point — so a planet only appears here when you could actually see it.
