Why it matters: A groundbreaking study has revealed the existence of a semi-molten “gooey” layer deep within the Moon, challenging previous assumptions about its internal structure and potentially impacting future lunar exploration efforts.
The discovery unveiled: Researchers analyzing data from NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission and the Lunar Reconnaissance Orbiter have identified a low-viscosity layer between the Moon’s mantle and core.
- According to Vice, this “Moon goo” layer experiences tidal movements due to Earth and the Sun’s gravitational forces.
- The layer’s existence suggests ongoing thermal activity within the Moon’s interior.
Key findings:
- Futurism reports that the “Moon goo” layer is located between the rugged mantle and metal core.
- It remains in a semi-molten state, according to Popular Mechanics, behaving similarly to a partial melt.
- The layer’s movement causes measurable changes in the Moon’s gravity.
Implications for lunar geology: This discovery provides new insights into the Moon’s thermal state and evolution:
- Supports theories of a softer layer at the base of the lunar mantle.
- Raises questions about mechanisms maintaining the layer’s temperature.
- Could influence our understanding of the Moon’s formation and history.
Looking ahead: The study opens new avenues for lunar research and exploration:
- Future missions may focus on better understanding the composition of this layer.
- Knowledge of the Moon’s internal structure could inform plans for permanent lunar bases.
- The discovery may lead to a reassessment of other celestial bodies’ internal structures.
As scientists continue to unravel the mysteries of our celestial neighbor, this “Moon goo” discovery marks a significant milestone in lunar geology. It not only enhances our understanding of the Moon’s complex interior but also paves the way for more informed and strategic approaches to future lunar missions and potential colonization efforts.
