Australian researchers have developed a new method for scanning the depths of planets.
This method only requires one seismometer operates on the surface of the planet, using Technology similar to ultrasound – uses sound waves to obtain images of the patient’s body, to confirm whether the planet has a core or not. This seismometer will measure specific seismic waves created by shaking of the planet’s surface.

Scientist Hrvoje Tkalcic from the Australian National University (ANU) Earth Sciences Research Institute, co-author of the study, emphasized that this is a new method that uses a tool unique to scan the interior of any planet, which has never been applied. Before. The research team conducted tests on Mars and determined that the Red Planet has a core approximately 3,620 km in diameter.
According to co-author Sheng Wang, confirming the existence of a planetary core can help scientists understand the past and future evolution of the planet, including the timing of its magnetic field. He said Models show Martian core is liquid, not only primarily iron and nickel, the core may also contain small amounts of lighter elements such as hydrogen and sulfur. These elements can change the core’s ability to transfer heat.
Therefore, researchers hope that this method can help improve the understanding of other celestial bodies, including the Moon.
This method is presented in detail in a report from the Australian National University.
