ARThe article discusses a new 3D map of Earth's gravitational field released by NASA, based on satellite observations. The map highlights variations in gravity caused by differences in mass distribution beneath the surface, such as mountain ranges and ocean basins. It explains that the representation, called a 'geoid,' does not show the planet’s physical appearance but rather magnifies vertical scale differences to visualize subtle gravitational changes. Scientists note that these variations are influenced by factors like water movement and ice melt, and the data helps study hydrological cycles, groundwater availability, and long-term sea level rise. The image was created using over 1 billion observations collected over 15 years by 19 satellites, combining data from ESA's GOCE mission and NASA's GRACE program.
