Apparently, star formation in ellipticals came and went eons ago.

Over the eons, this has cleaned out a lot of otherwise dangerous objects that could have eventually hit Earth.

The pictures it returned were breathtaking, and revealed a world that has seen a lot of pummeling over the eons.

它传回来照片令人叹为观止——展示了一个千万年来伤痕累累世界。

Over the eons, the summit collapsed and created a giant pit in the Earth, a super crater now known as the Yellowstone Caldera.

过了很久，峰顶塌陷，在地球上形成了一个巨大坑，一个超级火山口，现在被称为黄石火山口。

Or maybe it used to be one big lump, but over the eons the ice in the middle sublimated more, leaving behind the two lobes.

又或许它曾经是一个大冰块，但年后，其中间冰升华得更多，留下了两个叶瓣。

As we'll see in upcoming episodes, we're getting a pretty good idea of how the Universe got its start, and how it's evolved over the eons.

在接下来几集里，我们将会看到宇宙是如何形成，以及它是如何在漫长岁月中进化。

The extraordinary fact is that we don't know which is more likely, a future offering us eons of perishing frigidity or one giving us equal expanses of steamy heat.

一个明显事实是，我们不知道未来年代是一个严寒气候，还是一个酷热气候。

In the past, the Local Group probably had lots more galaxies, but over the eons the two big galaxies ate them all, growing huge.

在过去，本星系群可能有更多星系，但在漫长岁月中，这两个大星系把它们都吃光了，变得越来越大。

Eons ago, comets (and asteroids) may have brought a lot of water to Earth — as well as the ingredients for life.

很久以前，彗星(和小行星)可能给地球带来了大量水——以及生命成分。

" Dragon's eggs, from the Shadow Lands beyond Asshai, " said Magister Illyrio. " The eons have turned them to stone, yet still they burn bright with beauty. "

" 这是来自亚夏以东阴影之地龙蛋。" 伊利里欧总督说，" 历经千万年而成化石，却依旧亮丽动人。"

These remarkable hills owe their peculiar shapes to the mildly acid waters of the Li River, whose meandering course over eons of time has corroded away their basis, until only the rocky course remained.

这些神奇山地嶙峋奇秀归功于漓江那弱酸性水质，亿万年曲折线路已经侵蚀掉它们主要部分，直到只剩下坚硬河道。

Well for me, as a sculptor, the acceptance of the material as a means of conveying the relationship between human-lived biological time and in a way the eons of geological time, is an essential condition of the waiting quality of sculpture.

身为雕塑家，我认为原料材质反映了人类寿命生物时间与永恒地质时间之间关系，是雕像能够长存基本条件。
