New Findings Confirm Mars Has Solid Inner Core
Reading
Scientists have learned new things about Mars. They found that Mars has a solid metal core, like Earth. This was found using information from a NASA lander named InSight.
InSight was on Mars and listened for marsquakes. It recorded over 1,300 marsquakes before it stopped working in 2022. The lander was near the equator of Mars since 2018.
Earlier studies thought the center of Mars was liquid. Now, scientists think the inner core is solid metal. This solid core is surrounded by a liquid metal outer core.
The solid inner core of Mars is about 380 miles wide. It is likely made of iron and nickel. It may also have lighter things like oxygen inside it.
One scientist, Daoyuan Sun, said the core may be forming now. Mars used to have a completely liquid core. More research is needed to learn about Mars' magnetic field in the past.
