Scientists Uncover Moon’s Secret Origin Right Below Us
eureka moment: a moment of sudden insight or discovery
Hidden deep beneath our feet lies a secret as old as the moon itself. Two gigantic blobs, each one double the size of the moon, have been discovered near Earth’s core. For years, their origins puzzled scientists. Now, they believe these blobs are the remains of an ancient planet named Theia that once hit the Earth.
This crash was so huge that it also made our moon! Researchers think that when Theia hit the Earth, most of it went into Earth and formed the blobs. Some pieces flew off and became our moon.
Scientists learned this by looking at how earthquake vibrations move through Earth. They noticed that these waves go slower through the iron within the blobs. One scientist described the eureka moment when he realized the connection between the iron in the moon and the iron in these blobs.
Imagine that – traces of another world lying right under our feet.
