or stories of abduction by little green men,

including the possibility of extraterrestrial life,

以及其他地方存在生命的可能性

other worlds inhabited by known human beings,

So, planets within such a habitable range

生物只能存在「類地球環境」中

one of the most amazing discoveries of astrobiology

但其中天體生物學最迷人的發現

that'd be fatal for most known organisms.

這些環境讓大多數生物無法生存

Organisms that live in these challenging environments

What is most remarkable about these extremophiles

is that they are found thriving in environments

One of the most important of these worlds

就是我們紅色、塵土飛揚的鄰居：火星

Today, astrobiologists are exploring places

where life might once have existed on Mars

探討火星上 可能曾經存在生命的地方

Evidence from orbit suggest past traces of water,

軌道上的證據顯示過去曾有水的痕跡

For example, Europa, one of the moons of Jupiter,

there is evidence of liquid oceans beneath the shell.

Could life be floating around in these oceans,

or could it be living around black smoker

及和地球相仿的湖泊、海洋和河川

還有，相當重要地，碳組成的分子
