Star & sky tools
Free, no login, no app. The same real astronomy that powers our star map posters — pointed at whatever you want to know about the sky.
See the sky now
Set your location and look up.What's up right now from where you are — planets, bright stars, and constellations, updating live.
Which of the five naked-eye planets are up, when each rises and sets in your timezone, and which way to face.
Fly around the Sun, the planets and their moons, Pluto and the Voyagers, each where it is right now. Run time forwards and backwards, and tap any world for its story.
Whether tonight's northern lights are strong enough to reach your latitude, read from NOAA's live data.
Plan the year ahead
Never miss the good nights.Every meteor shower, eclipse, supermoon, and conjunction this year — and which are visible from you.
A live countdown to the next shower peak, with the best hours to watch in your own timezone.
A live countdown to the next time two planets pair up, and how well placed it is from where you are.
The next new moon, and which of the coming nights are actually dark where you are — moon-free hours, not just the phase.
Every 2026 full moon, its old name, which ones are supermoons, and your local moonrise time.
Made from a date
Turn a moment into a star map.The sky above your birth city the night you were born — stars, moon phase, and the planets that were up. Birth time optional.
Any night in history — an anniversary, a wedding, a moon landing. Pick a date, a time, and a place.
Every great comet since 1811 — Hale-Bopp, Halley, NEOWISE — and the night sky each one hung in.
Your zodiac sign, plus the constellation the Sun was actually passing through on the day you were born.
