The study found that the kernel's core is a strong \"generator \" in more than 3 billion years ago, which has a strong magnetic field, which is much higher than the globe's current magnetic field.
On December 9th, the foreign media reported on the 8th. The study found that the kernel's kernel was a powerful \"generator \" in more than 3 billion years ago, which has a strong magnetic field, far higher than the earth's current magnetic field.
The researchers of the Massachusetts Institute of Technology said that according to the current theory, the core of the celestial body should have a large amount of liquid metal substance. Like the inside of the earth, liquid metals circulate in a high temperature and high pressure environment, and the resulting energy is converted into an Earth's magnetic field.
The evidence shows that approximately 35.6 to 42 billion years ago, the kernel of the moon is a molten state, created a magnetic field that lasts nearly 1 billion years, and is strong than the magnetic field of the earth.
Earlier in Apollodeng, astronauts brought back rock samples from the surface of the moon. Astronomers analyze the samples, the moon core should have a super \"generator \" that generates a magnetic field.
However, scientists still can't explain how such a powerful moon magnetic field gradually disappears. If you can unlock this secret, you may predict the future development of the Earth's magnetic field.
