Researchers from China and the USA, contrary to long -established opinion, found evidence that Mars has a solid internal core.
Researchers from the Chinese University of Science and Technology and the University of Texas in the United States analyzed the seismic data obtained under the NASA Mission, which has already completed its own, which has already completed its work.
Scientists found that in the depths of Mars there is a solid internal core with a radius of 600 kilometers.
indicating the similarity of this solid mass equal to about 18% of the radius of Mars, with the internal core of the Earth, the researchers noted that the results of their work can serve as a guide for understanding the thermal and chemical state of the planet. The inner core is formed by condensation of light elements, such as carbon, oxygen and hydrogen that are separated from the outer core by crystallization.
in their opinion, the absence of a global magnetic field on Mars, despite its bark strongly magnetized in the past, indicates the cessation of the dynamic activity of the planet. Scientists have applied that crystallization of the nucleus and the presence of an internal nucleus can play a decisive role in understanding this process.
researchers emphasized that this work, which, contrary to previous opinions, shows that Mars does not have a fully liquid core, sheds light on long -standing discussions about the formation and evolution of the planet.
The study is published In the journal “Nature”.
