Dear MEL Topic Readers,
The moon is about 85 million years younger than we thought, new study finds
Do you have any idea how and when the moon was formed? According to a widely supported hypothesis, about 4.5 billion years ago, an ancient planet in the early Solar System collided with the early Earth when it was still heating up and changing rapidly. The collision created a lot of debris that orbited around Earth and later formed the early Moon. So, it has been widely assumed that the Moon was born about the same time as the Earth.
Now, a new study estimates that the Moon was formed about 85 million years after the Earth when the planet was almost formed solid. Also, it found that it took about 200 million years for the Moon to cool down and became solid from its molten form.
How did the scientists figure out these super ancient astronomical timelines?
Enjoy reading the article and learn about the birth of our planet and the Moon.
