NASA’s New 3D Model Shows the Earth Is a Lumpy Mess
Wednesday, July 29, 2026
NASA released a three-dimensional model of Earth's gravitational field that depicts the planet's surface as irregular rather than uniformly spherical. The model was created by mapping variations in Earth's gravitational field, which reflect differences in the planet's mass distribution. These variations occur due to factors including differences in rock density, mountain ranges, ocean trenches, and subsurface structures.
