【阅览】科普文
It is biochemistry—evidence of molecules made by life—that Mars has failedto provide. Four decades ago two Viking probes landed and subjected samples ofits surface to various chemical tests as a way of looking for life. The resultswere frustrating; not quite what was expected from lifelessness, but notseemingly compatible with life. For all the satellitesand rovers that havestudied Mars since, there has been no sign of so much as a bacterium.
没有根据证明火星上有生物资生的分子,因而(对)火星(的勘探)并未证明生命的存在。40年前,两架海盗号勘探器在火星着陆,并对表面物质进行了取样和化学查验以寻找生命体的存在。成果让人沮丧:(火星)并不是像咱们所预期的那样没有生命存在,而是如同并未供给适合生命生计的条件。自那之后研讨火星的卫星和勘探器均没有发现生命,就连细菌都没有发现。

frustrating让人沮丧的
seemingly看似……地
compatible with sth 跟……兼容的
satellite卫星
rover周游车
there has been no sign of … 全无痕迹
bacterium细菌
It is thus hardly surprising that interest in water elsewhere has risen.And it hasturned out that Enceladus, a small moon of Saturn (illustrated above)and Europa have it in abundance: Enceladus may have as much as Lake Superior.Europa may have more than the whole Earth.
所以科学家关于其他含水卫星的快乐喜爱大增也就缺乏为奇了。据证明,土星的一颗小卫星,土卫二(上图所示)以及木卫二有足够的水:土卫二的水量可以有苏必利尔湖那么多。而木卫二的水量可以比整个地球加起来还多。

Lake Superior 苏必利尔湖【闻夕注】美国五大湖之一
That may sound odd. Jupiter and Saturn are much farther from the sun thanMars is. The average temperature on Europa is a chilly -171°C. But sunlightisnot the only way to heat an astronomical body. Gravity can do it, too. To mostEarthlings,the tides produced by the gravity of the moon and sun matter only tosea levels. But the tides that a huge planet like Jupiter or Saturn can producein an orbiting mo
on are powerful enough to knead the rocks of the moon’s core,warming them up via friction. Such heating frombelow allows both Enceladus andEuropa to harbour oceans under their cold, icy surfaces.
这听起来可以很新鲜。木星和土星间隔太阳的间隔比火星远得多。木卫二的均匀温度为零下171°C,非常严寒。但太阳光并非让一个天体热起来的仅有途径,引力也可以。对大大都地球人来说,因为卫星和太阳的重力作用发生的潮汐只会对海平面发生作用。但对木星或土星这种大行星来说,其引力在绕其作业的卫星上发生的潮汐力气很大,甚至可以使卫星核内的岩石彼此冲突,致使卫星升温。这种由下而上的加热使土卫二和木卫二都能在其冰凉严寒的表面下蕴藏海洋。
