Planetary Observer

Planetary Observer follows what is happening on Earth and in space, as it happens.

The feed collects significant events from more than 55 scientific and government sources, including USGS, NOAA, NASA and ESA, and turns each one into a short story with the key numbers, maps and imagery. Every story names where its information comes from.

WHAT IT COVERS • Earthquakes and tsunami forecasts • Hurricanes and tropical storms • Volcanic activity and wildfires • Solar flares, coronal mass ejections and geomagnetic storms • Rocket launches, the International Space Station and missions to the Moon and Mars • Eclipses, asteroid close approaches and other sky events

EXPLORE THE GLOBE See every event pinned on an interactive 3D globe, and switch to Mars and the Moon to follow mission activity there.

VISUALIZATIONS BUILT FROM THE DATA Seismic wave maps, hurricane tracks, eclipse diagrams and daily space-weather video made from solar observatory imagery.

ALERTS YOU CONTROL Turn on notifications by category: severe weather, earthquakes with your own minimum magnitude, space weather and astronomy.
