# Hidden Volcanoes Reveal Moon's Turbulent Past NASA's discovery rewrites the geological history of our lunar neighbor. - **Source:** [Nature](https://brifing.si/source/4d850c3b-dd79-4024-bc91-db2571889199) - **Published:** 2026-08-20 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/3b77fe46-5358-4975-9135-ee5b98eec6f5 ## Discovery of Hidden Volcanoes NASA's Lunar Reconnaissance Orbiter has identified two previously unnoticed large volcanic structures on the Moon's surface. Named the Prinz-Harbinger volcanic shield, these formations span about 80 kilometers and are partially obscured by irregular terrain. This finding suggests the Moon's geological history is more complex than previously thought. ## False-Color Mapping Technique Researchers employed false-color mapping to highlight the volcanic features. This method accentuates mineralogical differences, revealing traces of volcanic activity. Although an impact crater in the lower left partially obscures the structure, advanced techniques made detection possible. ## Rewriting Geological History The discovered volcanoes indicate the Moon had a more active geological past than assumed. These findings raise new questions about lunar interior structure and magma dynamics. Scientists are investigating whether these volcanic processes differed from those on Earth. ## NASA's Lunar Missions The Lunar Reconnaissance Orbiter has been mapping the Moon's surface in detail since 2009. This discovery underscores the mission's ongoing importance. As NASA plans crewed flights under the Artemis program, such geological findings may influence future landing site selections. ## Scientific Publication Details The research was published in Geophysical Research Letters. The paper provides insights into magma storage conditions beneath these volcanic structures. The team is developing new theories about the timing of volcanic activity by studying disequilibrium responses in the Moon's crust. ## Global Scientific Collaboration The discovery was made by an international team led by Chinese scientist L. Qiao. The study was enabled by NASA's open data policy. Such collaborations highlight the importance of global knowledge sharing in space exploration. ## Lunar Volcanic Shields Similar to shield volcanoes on Earth, these formations were created by lava flows. However, the Moon's low gravity and thin atmosphere made these processes distinct. Scientists are working to determine how long these volcanoes remained active and when they became extinct. ## Importance for Space Exploration This discovery not only illuminates the Moon's past but also helps us understand the geological evolution of other planets. Reading volcanic signatures could become a critical tool in searching for signs of life on planets like Mars. ## Sources covering this story - https://www.nature.com/articles/d41586-026-02555-9 — --- _Summary written by Brifing from the original reporting.
