Description
Skyfield answers the question every sky-watcher actually has: what's in the sky tonight, when should I look, and is it even worth going outside?
Open it and get a straight answer for exactly where you are:
IS IT WORTH LOOKING UP TONIGHT?
A live Stargazing forecast — an honest Excellent / Good / Fair / Poor verdict and 0–100 score, from tonight's real cloud cover and the moon's brightness
Your best dark-sky window tonight, with real times ("clear and moonless 11:30pm–1am")
Sky Conditions now — temperature, cloud cover, and what the sky is doing
WHAT'S UP, AND WHEN
Sunset, golden hour and blue hour — to the minute
The moon's phase, how lit it is, and tonight's moonrise & moonset
The next meteor shower peak
Aurora chance for your latitude, from NOAA's live Kp forecast
"The Sun's Path" — a live arc of the sun across the day
YOUR AI SKY GUIDE
A new Guide tab reads tonight's real conditions for your location and gives 2–3 short, specific tips: what to look for, the best window to go out, and a sunset/photo tip. It always works — even offline, it falls back to clear, data-based guidance computed on your device. AI is optional and off until you turn it on.
Sky conditions use the free Open-Meteo and NOAA space-weather services; sun, moon and the stargazing forecast are computed on your device and work offline. No account, no sign-up, no tracking.
KEEP WHAT YOU SAW
Log a sunset, the full moon, an aurora, or a passing bird in seconds — with a photo and a note. Your year rolls up into a "Year in the Sky" recap to look back on and share.
BUILT FOR YOUR PHONE
Home Screen and Lock Screen widgets with tonight's moon and golden hour
Ask Siri or use Shortcuts: "What's in the sky tonight?"
Full Dynamic Type, dark mode, and accessibility support
Skyfield is free, has no ads, and asks for nothing. Just look up.
