NASA’s New 3D Model Shows the Earth Is a Lumpy Mess
- NASA released an exaggerated 3D model of Earth's uneven gravitational field
- Gravity satellite data tracks Antarctic and Greenland ice loss for sea level science
- Same data reveals severe drought behind current Spain and France wildfires
NASA has published a new 3D visualisation of Earth's geoid, revealing the true, irregular shape of the planet's gravitational field rather than the smooth "Blue Marble" image most people recognise. The lumps and dips shown are caused by uneven distribution of mass beneath Earth's surface, and the model…
