HorizonQuest

Space apps put the sky on a screen. HorizonQuest gets you outside under the real one — see tonight’s actual Moon phase, pick your part of the world, and learn the stars, planets, and patterns to look for, with five little sky guides.

🌙 See tonight’s sky 🔭 Learn the sky

Start here

Tonight See tonight’s real Moon phase, pick your part of the world, and get your naked-eye list to look for. Sky quiz Learn the Moon’s phases, wandering planets, and asterisms — then take it outside.

Meet your sky guides

Five little guides look up with you — each one is one thing to notice in the real sky.

  • Polaris the Patient — the North Star — the ONE star that never moves
  • Jupiter the Wanderer — planets wander — bright, steady, and slowly drifting
  • Luna the Shape-shifter — the Moon’s phases — new, quarter, gibbous, full and back
  • Sirius the Twinkler — why stars twinkle — their light dances through our air
  • the Belt trio — asterisms — little star patterns like Orion’s Belt

🔒 HorizonQuest never asks for your location, never uses the camera, and has no account or AI. Your sky journal stays on THIS device only. The best part happens with the screen down and your eyes up.
