Scientists find Mars likely has a solid inner core, similar to Earth's

Scientists discovered Mars likely has a solid inner core, similar to Earth's. This finding helps explain the planet's evolution and its lost magnetic field. The discovery, based on seismic data from NASA's InSight mission, suggests Mars' core structure is like Earth's, with a solid center surrounded by a liquid outer layer. This could have supported a magnetic field in the past. This research deepens understanding of planetary formation and Mars' transition from a potentially habitable world to its current arid state.
