The hydrogen sulfide reacted with oxygen in rainwater moving through the rock.

But the exoplanet was previously not thought to hold hydrogen sulfide.

但是，这颗系外行星此前被认为并不存在硫化氢。

Jupiter, too, has small amounts of hydrogen sulfide in its atmosphere.

木星大气层中也有少量硫化氢。

The action of oil and natural gas created hydrogen sulfide in the limestone.

石油和天然气作用在石灰中产生了硫化氢。

They're also monitoring the air for traces of hydrogen sulfide and sulfur dioxide.

他们还在监测空气中硫化氢和二氧化硫迹。

These gases are a death filled cocktail of hydrochloric acid, hydrogen, hydrogen sulfide, and sulfur dioxide.

这些气体是由盐酸、氢气、硫化氢和二氧化硫混合而成致命混合物。

To test the device, the researchers puffed it with different concentrations of hydrogen sulfide gas.

为了测试这个设备，研究人员使用了不同浓度硫化氢气体。

But, as they watched the beakers, a bunch of the hydrogen sulfide seemed to be disappearing.

但是，当他们观察烧杯时，一束硫化氢似乎正在消失。

Second, it's about what scientists say they've detected in the planet's clouds, hydrogen sulfide.

其次，这是科学家所，他们在地球云层中发现了硫化氢。

Like hydrogen sulfide, which smells like rotten eggs.

比如硫化氢，闻起来像臭鸡蛋。

So, in this case, the hydrogen sulfide could have lost electrons in a redox reaction.

因此，在这种情况下，硫化氢可能在氧化还原反应中失去了电子。

These sediments were anoxic, or poor in oxygen, and they were also full of hydrogen sulfide.

这些沉积物是缺氧或含氧量很低，并且它们充满了硫化氢。

It warned some communities about high levels of hydrogen sulfide gas escaping from the rotting algae.

它警告一些社区注意从腐烂海藻中释放出高浓度硫化氢气体。

In deep, dark ocean ecosystems, some bacteria use chemicals like hydrogen sulfide as their energy supply instead.

在深海、黑暗海洋生态系统中，一些细菌使用硫化氢等化学物质作为它们能量供应。

Hydrogen sulfide is a colorless gas that smells like rotten eggs.

硫化氢是闻起来像臭鸡蛋无色气体。

At super high concentrations, it can be toxic like hydrogen sulfide.

在极高浓度下，和硫化氢一样有毒性。

He noted, for example, that hydrogen sulfide would have been much harder to find on planets that are further away.

他指出，例如，在更远行星上，硫化氢会更难被发现。

In the aquifer's depths, a layer of clear fresh water sits atop salt water that's saturated with toxic hydrogen sulfide.

在含水层深处，一层清澈淡水就浮在充满有毒硫化氢咸水之上。

Like, in this case, it connects the hydrogen sulfide reducers in anoxic sediment with oxidizers closer to the surface.

同样，在这种情况下，它将缺氧沉积物中硫化氢还原剂与靠近表面氧化剂连接起来。

New observations by NASA's James Webb Space Telescope suggest that this is the first exoplanet where hydrogen sulfide has been identified.
