Thundering earthquakes are seen on Mars. Due to which the scientists decided to find out what the heart of Mars, i.e. the core, is made of. With a recent research, scientists have found out what is in the core of Mangar.
NASA’s InSight lander monitored the interior of the Red Planet for four years. According to the seismic data obtained from this, the center of Mars is a liquid iron alloy, in which a large amount of sulfur and oxygen is mixed.
With this information, scientists can better understand the history of Mars and learn why it is different from Earth, Mars is a dry, lifeless ball of dust while Earth is green.
Vedran Lekic, a geologist at the University of Maryland, says that in 1906, scientists discovered the Earth’s core for the first time. More than a hundred years later, we are applying our knowledge of seismic waves to Mars.
While monitoring the interior of Mars, InSight detected hundreds of earthquakes in a short period of time, giving us insight into the interior of Mars. With this, scientists were able to compile the first detailed map of the core of Mars and learn more about the state of Mars’ internal activity.
Talking about the Earth’s core, its outer outer core is liquid, the inner core is solid and then the innermost inner core is even denser. Researchers found that unlike Earth’s core, Mars’ core is liquid on all sides. And a large amount of light elements are found in the inner core of Mars. About one-fifth of its weight is made up of these elements, especially sulfur and smaller amounts of oxygen, carbon and hydrogen.
This means the core is less dense and more compressed than Earth’s core, allowing scientists to better understand the differences between the two planets.
We know that Mars does not have a global magnetic field. On Earth, the magnetic field helps keep the atmosphere and water from leaking out into space. The geodynamo effect is generated in the core of the earth. The heat moves from the inner core to the outer core, creating currents and changing patterns under the influence of the planet’s rotation. This is what creates and maintains the magnetic field.

In previous research, scientists had told that the presence of light elements in the core of Mars would have played an important role in eliminating its dynamo and magnetic field. We now have enough information about what’s really out there, so that scientists can better reconstruct the history of Mars. This research has been published in the Proceedings of the National Academy of Science.
