The planet our Earth may have 'devoured'

地球可能 “吞噬” 过的一颗行星

文字稿

Did Earth devour a nearby planet called Theia?

地球是否 “吞噬” 过一颗被称为 “忒伊亚” 的邻近行星？

It's part of a leading theory for how our Moon was formed.

这是关于月球形成的一个主流理论。

Most astronomers think Theia and a young Earth collided about 4.5 billion years ago.

大多数天文学家认为忒伊亚和早期的地球在大约 45 亿年前相撞。

This would have released enough material to clump together into the Moon.

这次撞击释放出了大量的物质，它们随后凝聚成了月球。

Prof Thorsten Kleine, Planetologist, Max Planck Institute
"That was the case during the planet formation process, you know, when the entire system was unstable."

索斯滕·克莱恩教授    行星学家，马克思·普朗克研究所
“这发生在行星形成的过程中，当时整个太阳系都处于不稳定的状态。”

Part of Theia might have been absorbed by the Earth.

忒伊亚的一部分可能被地球吸收了。

And scientists even claim to have found some of it buried deep inside the planet.

有些科学家甚至宣称已经在地球深处找到了部分被埋藏的忒伊亚残骸。

Regardless, it seems we might owe Theia, and the Moon, a lot.
无论如何，看来我们如今拥有的一切，很大程度上都要归功于忒伊亚和月球。

Prof Thorsten Kleine, Planetologist, Max Planck Institute
"It's very important for the climate's stability. If we [did] not have this, I think we would have much more extreme climate and weather conditions, which would not be good for the development of life. Understanding the Moon, or the origin of the Moon, is important for understanding why the Earth is as it is, and why it is basically a planet that can harbour life."

索斯滕·克莱恩教授    行星学家，马克思·普朗克研究所
“这次撞击对气候的稳定十分重要。如果不是因为这次撞击，我认为我们就会面对更加极端的气候和气象条件，这不利于生命的演化。了解月球，或月球的起源，对于理解地球为何会演变成今天的样貌，以及为何它能成为一颗孕育生命的星球至关重要。”
