Unveiling Mars' Surprising Molten Layer Above its Core

Two new papers published in Nature reveal that Mars has a molten silicate rock layer, approximately 150 kilometers thick, surrounding its liquid iron-alloy core. This challenges previous assumptions about the size and composition of Mars' core, suggesting that it is smaller and denser than previously thought. The seismic data collected by the Mars InSight lander provides valuable insights into the planet's interior structure and could help scientists understand Mars' history and evolution. Further research is needed to unravel the mysteries of Mars' past and its transformation into the arid and lifeless planet we see today.

Unveiling the Composition of the Moon's Core: Scientists' Groundbreaking Discovery

Scientists have determined the composition of the moon's core through a study that analyzed simulations and data from NASA's GRAIL mission. The moon's core is found to be a solid metal ball covered by a molten outer layer, similar to Earth's core. The study's findings provide valuable insights into the moon's formation and will aid in future lunar exploration efforts.

Uncovering the Secrets of Mars' Core: New Study Reveals Differences with Earth

Seismic waves have been detected traveling through the core of Mars for the first time, revealing details of the composition of the Red Planet's heart. The seismic data was collected by an international team of researchers using NASA's InSight Mars lander and it reveals the Martian core to be composed of a completely liquid iron-alloy core with high percentages of sulfur and oxygen. This grants a better understanding of how Mars formed in the infant solar system around 4.6 billion years ago and illustrates some of the key geological differences between the Red Planet and Earth, which may ultimately help explain why Earth can support life but Mars cannot.

NASA's InSight mission reveals secrets of Mars' liquid core.

NASA's InSight lander has discovered that Mars has a completely liquid core, rich in sulfur and oxygen, offering new insights into Mars' formation, its differences from Earth, and the implications for planetary habitability. Scientists observed seismic waves traveling through Mars' core for the first time and confirmed model predictions of the core's composition. Mars' core is less dense and lacks a protective magnetic field, suggesting that it may have evolved from a potentially habitable environment to its current hostile state.

NASA's InSight mission reveals seismic activity and potential for life on Mars

Scientists have detected seismic waves traveling through Mars' core for the first time, confirming model predictions of the core's composition. The team found that Mars has a completely liquid iron-alloy core with high percentages of sulfur and oxygen, indicating different conditions of formation for the two planets. The findings reveal new insights into how Mars formed and the geological differences between Earth and Mars that may ultimately play a role in sustaining planetary habitability.
