Scientists can't believe what they've discovered on Mars: "It means it's more like Earth than previously thought."

A major discovery published in the scientific journal Nature is revolutionizing space research, specifically on Mars, after the discovery of a solid core on the red planet.

Of all the planets in the solar system, the study and research of Mars is the most important , because it is the most Earth-like place in existence . And since humans have been searching for a "planet B" that meets the necessary characteristics for life for years, researchers have placed a strong focus on it.

And in recent weeks, scientists on NASA's InSight mission have made an important discovery of a sphere approximately 1,200 kilometers in diameter, which shows that Mars not only has a liquid core, as was thought, but also has a solid inner core, similar to that of Earth.

This is significant because it redefines our understanding of the Red Planet's internal structure and evolution, and has direct implications for future research into its formation, history, and potential for life . Researchers used a method using PKKP and PKiKP waves using seismic data from the InSight mission, which also happened to be the same method that led to the discovery of Earth's solid core.

Although this discovery indicates the presence of elements such as iron, oxygen, sulfur, and carbon, which suggests a chemical evolution distinct from that on Earth, this helps explain why Mars lost its global magnetic field billions of years ago, becoming a desert unprotected from solar radiation.

This discovery, which has yet to be fully verified, tells us that Mars was once filled with water, with rivers, seas, and consequently life , similar to Earth, but that something happened that turned it into the red, arid desert we all know.
