太阳系中所有的彗星都可能来自同一个地方

新的证据表明，太阳系中所有的彗星都可能来自同一个地方

All the comets in our Solar System may share the same origin story - and it could help explain how life on Earth came to exist.

我们太阳系中所有的彗星可能都有相同的起源，这可能有助于解释地球上的生命是如何形成的。

A team of American and European scientists found that 14 different comets originated at the same time and place: a protoplanetary disk orbiting near our newly-formed Sun, according to research that'll be published by the journal Astronomy & Astrophysics.

一个由美国和欧洲科学家组成的团队发现，14颗不同的彗星在同一时间和地点诞生:一个围绕我们新形成的太阳运行的原行星盘。这一研究结果将发表在《天文学与天体物理学》(Astronomy & Astrophysics)杂志上。

Given that comet impacts are thought to be a potential source of organic materials on Earth, exploring this new cosmic origin story could lead to a better understanding of the origin of life.

考虑到彗星撞击被认为是地球上有机物质的一个潜在来源，探索这个新的宇宙起源故事可能会让我们更好地理解生命的起源。

This particular survey of 14 comets is too small in scale to use as evidence that all comets came from the same time and place in the early Solar System.

这项对14颗彗星的特别调查规模太小，不能作为所有彗星都来自太阳系早期同一时间、同一地点的证据。

But it is an interesting starting point for future research, given that the researchers didn't expect to find so much in common among their samples in the first place, according to a Leiden University press release.

但莱顿大学的一份新闻稿称，这是未来研究的一个有趣起点，因为研究人员一开始并没有预料到他们的样本中有这么多的共同点。
