After extensive studies, scientists have put forth a theory stating that the moon once might have had a ‘dynamo’ or a molten metal core which could yield a magnetic field stronger than the Earth.
Scientists think that they may have put an end to the 40 year old mystery regarding the un-cited reasons surrounding the rocks collected by NASA’s Apollo astronauts as to how they became magnetized. They theorized that the moon despite having a mass of 1 percent as compared to the Earth contained within itself a molten metallic flowing core which might have had the capacity to generate a global magnetic field.
However, some researchers don’t agree to this, citing reasons that the lunar soil picked up magnetic fields from other impacting asteroids and bodies giving it repeated magnetized effects that shoot up and down.
These new findings pave way to the idea that not only did the moon once had a magnetic heart, but also it was way more into love than what our Earth is today. The study while based on reanalysis of Apollo samples coupled with more data collected from robotic probes, depicts that the moon had a dynamo driven heart some 4.2 to 3.6 billion years ago.
