MXThe article discusses a new three-dimensional map of Earth's gravitational field released by NASA, based on satellite observations. The map reveals that Earth's shape is less symmetrical than commonly believed, showing variations due to differences in mass distribution beneath the surface. It explains that the representation, called the geoid, illustrates the mean sea level if water were completely still, taking into account rock, magma, and water masses. Scientists clarify that this is not a visual image of Earth’s surface but a scaled-up illustration highlighting gravity variations. The data was processed using over a billion observations collected over 15 years by 19 satellites, combining data from the European Space Agency’s GOCE mission and NASA’s GRACE program. The map highlights significant variations, such as up to 85 meters in Iceland and down to 106 meters below sea level in southern India.
Bias read (Center): The article presents scientific findings without overt ideological framing. It focuses on technical explanations and data from reputable institutions like NASA and ESA, maintaining neutrality in its presentation of facts.
