The mystery of the Moon's inner core has finally been solved! Scientists have confirmed that it is a solid ball with a density similar to iron, surrounded by a liquid outer core. This discovery sheds light on how our solar system formed. 👇
Do you ever look up at night and wonder what is on the moon, or what it is even made of? The mystery of the moon's inner core has been around for centuries. Now, scientists have finally confirmed what it looks like., has revealed that the inner core is a solid ball with a density similar to that of iron, surrounded by a liquid outer core—a finding that will help us better understand how our solar system formed.
The discovery was made by analyzing data from NASA's Gravity Recovery and Interior Laboratory mission, according to. The agency sent two spacecraft into orbit around Earth's satellite in 2011, and these probes measured gravitational forces between them as they flew over different parts of their surface, allowing scientists to determine where each one was located relative to its partner based on those readings alone.
NASA's Apollo missions in the 1960s and 1970s obtained seismic data that was too imprecise to accurately determine the inner core's state. Still, NASA has announced that they've found evidence for an iron-rich core under about 1,700 miles of silicate mantle rock, at least as deep as Earth's core—and possibly much deeper than that.Arthur Briaud and his colleagues collected data from space missions and.
The researchers also calculated an average density for each hemisphere based on measurements taken by NASA's Gravity Recovery and Interior Laboratory mission, which involved two spacecraft orbiting around our satellite from 2011-2012.
