So I'm going to take a sample...
我要取一點樣品
here...
這里
dunk in the pH probe
插入檢測探針
and we see that it's dropped below 3 already,
可以看到數值已經小于三
2.7
2.7
and it's levelling off at about 2.65, so that's acidic.
穩定在2.65左右 呈酸性
That's about 100,000 times more acidic than a normal river.
比普通河水的酸性強十萬倍
And that's almost as acidic as stomach acid.
幾乎和胃酸一樣強
That is one acidic river.
這可真是一條酸河
If liquid water ever existed on Mars,
如果火星上真的有液態水
it might well have been a metallic acid river like this.
或許也會像這條河酸性一樣強
It seems unlikely to think that life
在如此惡劣的環境中
could have emerged in such a hostile environment,
很難想象會有生命存在
but scientists have discovered this blood-red river
但是科學家發現在血紅色的河水中
is actually teeming with microscopic bacteria.
充滿了細菌
This is a microscope photograph of the river water
這是顯微鏡下的河水
and you can see these thin,
你可以在顯微鏡下
hair-like threadsdown the microscope,
看到這些頭發般的細線
and these are the microbial filaments themselves,
它們是菌絲
these are the cells, these are the life in this water.
它們就是細胞 是水中的生命
