15 Fascinating Discoveries About What is Inside the Moon


The Moon has always captivated humanity. Its beauty has inspired myths and science. While we’ve marveled at its beauty from afar, the mysteries hidden within its depths have remained shrouded in enigma. After years of research, scientists have uncovered some of its secrets. Learn about 15 groundbreaking discoveries that reveal what’s inside, shaping our understanding of the universe.

Molten Core


Beneath the Moon’s serene surface lies a dynamic world. Scientists have confirmed the presence of a molten core akin to Earth’s, composed of iron and other elements. This revelation reshapes our understanding of the Moon’s geological history and potential for future exploration.

Lunar Quakes


Seismic monitoring has revealed the occurrence of moonquakes, providing insight into the Moon’s internal dynamics and tectonic activity. These lunar tremors, caused by the gravitational influence of Earth and meteorite impacts, offer valuable data for comprehending the Moon’s structure and evolution over billions of years.

Crystalline Caves


Scientists have discovered vast networks of crystalline caves deep within the Moon’s crust. These formations, created by ancient volcanic activity and meteorite impacts, could serve as potential shelters for future lunar colonies, shielding astronauts from radiation and extreme temperatures.

Water Ice Deposits

Dark, frigid regions near the lunar poles harbor volatile compounds, including water ice, ammonia, and methane. The sun-deprived areas near the lunar poles hold valuable clues to the Moon’s volatile history and serve as reservoirs of frozen resources, offering interesting prospects for future lunar exploration and habitation.

Lunar Regolith


Analysis of lunar soil samples has unveiled the composition and characteristics of the Moon’s regolith, the layer of loose, fragmented material covering its surface. Scientists gain key insights into the geological processes that shaped the Moon’s formation and evolution by studying the regolith’s chemical makeup and physical properties.

Lunar Magnetic Field Origins


The origin of the Moon’s magnetic field has long challenged astronomers. Recent simulations suggest that interactions between the solar wind and the Moon’s surface materials could generate transient magnetic fields, providing a new perspective on lunar magnetism and its evolution over time.

Lunar Dust Dynamics


Fine dust particles blanket the lunar surface, shaped by electrostatic forces and micrometeoroid impacts. Understanding the dynamics of lunar dust is crucial for future findings, as it poses issues for equipment and human health while offering insights into lunar geophysics.

Lunar Impact Basins


The Moon’s surface bears the scars of countless impact events, resulting in vast basins and craters that record its tumultuous history. By studying these impact features and their distribution, scientists reconstruct the timeline of major cosmic collisions that have shaped the Moon’s surface over billions of years.

Lunar Tides


The Moon’s gravitational influence affects Earth’s tides and creates tidal forces that shape its surface and interior. Astronomers have mapped out lunar tidal patterns, revealing the subtle yet significant changes in the Moon’s shape and orientation caused by the gravitational tug-of-war between Earth and its celestial companion.



Apollo astronauts left behind retroreflectors on the Moon’s surface, enabling precise measurements of lunar distance and Earth-Moon dynamics from Earth-based observatories. These lunar mirrors serve as enduring symbols of human exploration and scientific achievement, facilitating ongoing research in astronomy, geodesy, and fundamental physics.
