(单词翻译)

 This could be the most terrifying sight in the solar system: clear skies above a bottomless pit, an infernal drop into the depth of Jupiter’s endless sky.

 
You may have raindrops evaporating into the hot interiors of Jupiter, but there is no ocean down there. There is nothing now but just hot, more hot atmosphere.
 
Transmission was lost about 100 miles below the cloud tops.
 
Just hours after we lost contact with the probe, it descended1 into the part of the atmosphere where the probe material itself would have a sort of evaporating, so in sort of an examined closure, our atmospheric2 probe became part of the atmosphere for the studying.
 
Heroic as the descent was, the probe penetrated3 only the outermost4 onionskin of Jupiter, peeled back the layers that Galileo couldn't reach, and the mysteries / deepened.
 
We must now travel to the very strange heart of Jupiter to answer a true cosmic puzzle. How a gas giant is born? There is no boundary to run into, no concrete surface. But far below the clouds, the pressure squeezes hydrogen from a hot gas atmosphere into a hot liquid ocean. It’s deep. Keep going down another 12,000 miles and the liquid transforms again into something even stranger.
 
Temperatures and pressures would get to the point where protons lose track of / electrons and nuclei5 lose track of the electrons. And you basically just have a kind of a yummy, yummy soup, which is very hard to imagine. It’s just like trying to imagine yourself being inside of a star basically. Hydrogen, for instance, goes into what we call a metallic6 state. It’s the electrically conducting ‘food’ that’s causing Jupiter’s immensely powerful magnetic field.
