Pale Blue Dot

Pale Blue Dot turns your phone into a real-time model of Earth and the sky around it: a calm, beautiful place for curious kids (and grown-ups) to explore our planet and see how it works.

Spin the globe with your finger and watch day turn to night, with city lights glowing on the dark side. Tap anything to find out what it is and why it happens.

🌍 EXPLORE A REAL-TIME EARTH
• Day and night lit by the real Sun and synced to your clock
• Clouds from NASA satellite imagery, a generated offline view, or none at all
• Tap the glowing dots to learn about recently reported earthquakes, volcanoes, wildfires and storms, each with its date and source
• Tap any land or ocean to find out if it's day or night there, and why
• Show tectonic plate boundaries and see why earthquakes and volcanoes line up
• Watch animated auroras glow near the poles

⏳ TRAVEL THROUGH TIME
• Slide the clock up to a day forward or back and watch sunrise sweep across the planet
• Pick any date within a year to compare the seasons: see why June is summer in London but winter in Sydney
• One tap brings you back to now

🔭 A POCKET NIGHT SKY
• Thousands of stars, the Milky Way and 15 constellations in their real positions
• The Sun and Moon placed by astronomy, with arrows that bring them into view
• An illustrated orbit of the International Space Station
• Alerts when the Sun and Moon line up for a possible eclipse

📖 LEARN BY EXPLORING (made for ages 9–12)
• Every tap explains the science in kid-friendly words
• Three guided journeys: follow the sunrise, explore the Ring of Fire, and understand the seasons
• Collect discoveries in your own Field notebook. Can you find them all?
• Find-it challenges that build real thinking
• A new "Today" each day with the Moon's phase and a fresh space fact
• Read-aloud narration, plus calm ambient music with its own volume slider

📍 YOUR PLACES
• Save your town or anywhere you like: pick from 300 world cities, or tap any spot on the globe
• See whether it's day or night there, with local sunrise and sunset times

🏠 EARTH ON YOUR HOME SCREEN
