    2016行星大事記——水星、金星與火星

    Hey folks, it’s Lee Billings at Scientific American joined by my esteemed colleague...

    大家好,我是《科學美國人》的李·比林斯,這位是我的同事尊敬的……

    And together we’re going to give you a very quick rundown of what’s up in the solar system in 2016.

    今天我們將一起帶您快速概覽2016年太陽系發生的事。

    Yeah, so let’s start with Mercury, closest planet to the sun. Astronomers have discovered a colossal canyon, twice as deep as the Grand Canyon. Mercury is gradually shrinking as it cools. And as it shrinks it crumples up, like a grape shrinks into a raisin, and making those little crevices—except this is a really big crevice.

    我們首先來看離太陽最近的行星——水星。天文學家在水星上發現了一個巨大的峽谷,其深度是科羅拉多大峽谷的兩倍。由于氣候變冷,水星正在逐漸萎縮。水星萎縮時會起皺,就像葡萄收縮成了葡萄干,同時產生一些小凹縫——除了這一個非常大的裂縫。

    Wild. Now, Venus isn’t shrinking, is it?

    狂野!那么,金星沒有萎縮吧,對吧?

    Venus is not shrinking, but it is showing evidence that it might once have had oceans where life could have existed before the temperature went up to 900 degrees. And life could still be persisting in the clouds, and we could actually go look for it.

    金星并沒有收縮,但金星上發現的證據表明,在溫度上升到900度之前該行星上曾經有過海洋,而海洋中可能有過生命存在。而且在金星云層中可能還有生命仍然存在,我們甚至可以去那里尋找生命。

    Okay. We are going to skip over Earth, I guess; no one cares about Earth in the context of space. But lead us to Mars!

    嗯,我想我們將跳過地球。談論太空時,應該沒有人想說地球吧。不過,請帶我們去火星吧!

    The Mars Reconnaissance Observer has discovered an ice sheet 560 feet thick and has as much water as Lake Superior. So if you ever get to Mars to live, you’ll have a place to drink.

    火星偵察觀測器發現了一個560英尺厚的冰層,它的含水量和蘇必利爾湖一樣多。因此,假如你要去火星生活的話,那里就是你的水源地。
