Terella: Living Earth

BE Engineering

About this app

The world is more than a map. Spin Terella's interactive 3D globe to explore weather, climate, oceans and news together. See where the planet is changing — and where the world's attention is turning.

Turn curiosity into discovery: rotate, zoom, search for a country and tap the globe for details.

EARTH, FROM DAY TO NIGHT
Follow the day–night boundary, discover city lights on the night side and check local solar time in country cards. Watch the ISS move around Earth and explore upcoming space launches and aurora probability on the night side.

WEATHER YOU CAN EXPLORE
Trace wind and jet-stream patterns, view daily satellite cloud cover and explore modelled precipitation, dust and aerosols. Tap these layers to read available model values, including wind speed and direction. Compare available recent time steps for wind, rain and aerosols.

CLIMATE AND OCEANS IN CONTEXT
Compare each country's recent temperature with its own 20-year normal. Discover ocean regions warmer or cooler than their normal and tap currents to see speed and direction. Sea-surface temperature anomalies are broad regional estimates, not precise readings at your location.

THE WORLD'S ATTENTION
Explore the tone and volume of reporting about each country, along with where coverage originates. Country cards bring news indicators, temperature context, local solar time and the nearest earthquake together. Red means negative reporting, not proof that bad events are happening there. Terella shows news attention, not a news-reading archive.

A PLANET FULL OF CONNECTIONS
Explore earthquakes, satellite-detected heat hot spots and active cyclone, flood and volcanic hazards. Follow seasonal migration paths from published tracking studies. These are recorded animal journeys, not live individual tracking.

MADE FOR EXPLORATION
Eight interface languages: English, Turkish, German, French, Spanish, Italian, Japanese and Portuguese. A colour-blind-friendly palette offers an alternative way to read news tone.

KNOW WHAT YOU ARE SEEING
Observations, forecasts and research archives have different update times. Satellite clouds are a fixed daily composite, not live video. Source labels and timestamps help put the data in context. Terella is for discovery, not navigation or emergency decisions.

BUILT TO BE QUIET
No account. No ads. No analytics. No in-app purchases. Your touches stay on your device. If you allow approximate location, one low-accuracy reading is used only on the device to begin with your country facing you. It is never stored or sent.

Data sources and attribution are shown inside the app. They include GDELT, USGS, NASA, NOAA, GDACS, The Space Devs and the Movebank Data Repository.

What’s new

Simplified the news view by removing the History filter. Weather-layer time controls remain available. Refined globe opening and location-permission handling, with clearer regional ocean-temperature explanations.
