"Unveiling Planetary Secrets: Gravity Data Reveals Hidden Density Anomalies"
Originally Published 2 years ago — by Phys.org
Researchers have developed a new technique called THeBOOGIe (transdimensional hierarchical Bayesian object-oriented gravity inversion) that uses gravity data to infer the internal structure of planetary bodies. Unlike traditional methods, THeBOOGIe allows for more flexibility in inputting geological and geographical data and does not require a depth range or information on known internal density interfaces. The technique applies a Bayesian statistical approach to refine a randomly generated model of a planet or moon's interior until it best fits the input data. The researchers successfully tested THeBOOGIe on synthetic lunar data, accurately identifying the location and width of density anomalies in the lunar crust and mantle. The technique shows promise for visualizing the interiors of planets and moons lacking seismic and geophysical data.
