On June 4th we told you about iron snowflakes雪花 on Mercury水银. （6月4日我们向你介绍了？）Today we have some radical基本 news about the atmosphere of Venus.（今天我们将向你介绍一些关于金星大气的基本新闻。） Literally, a radical is a molecule that reacts easily with other chemicals because of an unpaired electron.（精确地说，因为有孤电子，所以分子中的基团与其他化学物质反应更加容易。） Astronomers have found the hydroxyl radical in the Venusian atmosphere.（天文学家已经发现在金星大气中存在羟基。） Hydroxyl is oxygen with a single hydrogen, H1O if you like.（如果你愿意的话，可以将羟基看作是是一个氧原子和一个氢原子） The Venus Express probe discovered hydroxyl in the clouds that shroud the planet. （金星快车探测器在金星高空发现了羟基，并且覆盖着星球。）Researchers from the European Space Agency announced the finding in the journal Astronomy and Astrophysics Letters. （来自欧洲航天局的研究人员声称这个发现已经天文学期刊中发表。）Hydroxyl is important on Earth, because it promotes the formation of ground-level ozone, a pollutant. Finding the radical on Venus will help scientists test their models of Venus’s atmosphere.（在地球上羟基是非常重要的，因为从羟基可以外推出有近地臭氧层的存在。）Hydroxyl also exists in the thin Martian atmosphere where it’s thought to stabilize carbon dioxide and prevent it from becoming carbon monoxide.（羟基同样也存在于细胞的火星大气中，这被认为可稳固二氧化碳，并且防止它转化成一氧化碳。） It may also be responsible for sterilizing the red planet’s top layers of soil.（这也是形成火星表层无菌土壤的原因。）

Thanks for the minute. For Scientific American’s 60-Second Science, I’m Steve Mirsky.
