我們怎麼知道外星行星的空氣是什麼樣的呢？ (How Do We Know What Air is Like on Other Planets?)
- and HD 209458b, a Jupiter-sized exoplanet orbiting the star HD 209458, which is 154 light-years away, has an atmosphere that contains hydrogen, carbon, oxygen, sodium, carbon dioxide, methane, and
的木星大小的系外行星，擁有一層大氣
- that contains hydrogen, carbon, oxygen, sodium, carbon dioxide, methane, and even water vapor.

- and they emit methane as their waste product: methanogens, methane generators.
而原核生物則沒有細胞核和膜狀胞器
- which is pretty cool and they emit methane as their waste product.
這相當特別，另外在這過程中它們會排出副產物甲烷
2089天內可能發現外星生命！🚀 (We Might Find Alien Life In 2089 Days)
- Organisms can use methane, carbon dioxide, sulfur reactions.
生物可利用甲烷、二氧化碳和硫發生反應。
- Organisms can use methane, carbon dioxide, sulfur reactions.
事實證明，我們也可以為天體做類似的事情。
飛機可以用氫氣當燃料嗎？！ (Could planes run on hydrogen?)
- There are various ways to do this, but the most common is steam-methane reforming, or SMR.
國際航空運輸協會的會員航空公司已承諾在2050年前達成淨零排放。
- The process heats and pressurizes methane from natural gas to isolate hydrogen atoms.
但由於航空業是最難脫碳的產業之一，這將不會是一項容易的任務。

- Like extremophile microbes on Earth, they found ways of breathing methane and using exotic enzymes to harvest sulphur and nitrogen compounds from the air.
只是這裡的水更多，而且熱氣騰騰。
- Deeper down in the planet, like extremophile microbes on Earth, they found ways of breathing methane and using exotic enzymes to harvest sulfur and nitrogen compounds from the air.
在行星更深處，就像地球上的極端微生物一樣，牠們找到了呼吸甲烷並利用外來酵素從空氣中獲取硫和氮化合物的方法。

- This world is covered in methane gas.
我們必須希望，如果我們能熬過危險……
- This world is covered in methane gas.
這個世界被甲烷氣體覆蓋。

- So on climate change, the example that I have is making cows fart less methane.
是以，關於氣候變化，我的例子是讓奶牛少放甲烷屁。
- So the, yeah, this is a project that, you know, a lot of scientists have come to recognize that one of the most significant contributors to global carbon emissions in the form of methane, which is a powerful greenhouse gas, is the farming of animals.
所以，這是一個項目，你知道，很多科學家已經認識到，甲烷是一種強效溫室氣體，而造成全球碳排放的最主要因素之一就是動物養殖。
氣候變遷是誰的錯？又是誰該負責解決？ (Who Is Responsible For Climate Change? – Who Needs To Fix It?)
- We're also pumping out growing volumes of other greenhouse gases, such as methane and nitrous oxide.
我們也排放了越來越多的其他溫室氣體，像是甲烷和氧化亞氮。
- we're also pumping out growing volumes of other greenhouse gases such as methane and nitrous oxide.
