英语听力：自然百科 行星旅行指南：木星 Jupiter—11

 If gravity measurement showed no solid core, then Jupiter formed early like the Sun, with a core then its birth came later when solid materials were created. By measuring water content, Juno should also reveal how hot the solar system was, when Jupiter formed and where. Some theories suggested the planet muscled its way in to be closer to the Sun. With gas giants like Jupiter being discovered now, all over the galaxy¹, resolving the puzzle of its origin, is taking on a whole new significance. 

 

  Arriving at Jupiter and looking for somewhere to land? A moon with a view perhaps. Choose carefully from the 62 solid surfaces on hand, some destinations out here are red hot. 

 

  While the atmosphere probe was disappearing into clouds in 1995, Galileo itself skimmed past moon Io, put on the brakes and slipped into orbit around Jupiter. Even at this stage the team knew that Io, about the same size of our own moon, would be one of their prime attractions. This strange pizza-colored moon, orbits the closest of Jupiter’s big four moons and its volcano central. 

 

Well this was one of those cases where the headline for the daily tabloid² is actually correct. It supposed volcanic³ places in the solar system. 

  

  There isn’t any place on the surface where we’re going to find a volcano within a hundred miles or so, usually less. And there is enough material coming out of those volcanoes to cover the surface over to a depth of  a centimeter every year. 

  

 

  Fresh-faced Io has a makeover between every visit. No other world masks its age so well. 

 

  We were lucky enough to point to (the) volcano that happened to be having a major eruption⁴ at the time. We saw this line of fire fountains actually so bright that they overexposed the camera and produced a very dramatic evidence of just how active Io was.
