正确答案:A 解析:今年NASA将研究外太阳系的两大行星Jupiter和Mars,讲话者多次使用这两个词的上义词,如planet,celestial bodies,而且,讲话者用上义词“the gas giants in the outer solar system”来指Jupiter,由此可知Jupiter是外太阳系的气态巨行星。NASA,美国国家航空航天局,成立于1958年,其前身是美国国家航空咨...
Is Jupiter a gas planet? Yes, but don't be fooled into thinking that Jupiter is like a big cloud of gas that you could fly through, it's more like a fluid planet that gets denser and hotter the deeper you go. Pressures at the colorful cloud tops are not dissimilar to those in Eart...
"It was a difficult challenge as the planet is incredibly faint and extremely far away," Norris said. "The big question was, how could we be sure we were seeing a forming planet, and not just a particularly dense clump of dust?" "The key is that, because of the energy of its rapid...
It has been theorised that the gas giant is a failedstar, that was not big enough to start the chain reactions that would allow it to fuse hydrogen into helium. When it comes to being a star, it is all about mass rather than size. The smallest star so far discovered is EBLM J0555...

Jupiter has no solid surface—hence, no topographic features—and the planet’s large-scale circulation is dominated by latitudinal currents. The lack of a solid surface with physical boundaries and regions with differentheat capacitiesmakes the persistence of these currents and their associated cloud ...
These prograde moons were tougher to spot than the outer retrograde Jovian moons. "The reason is that they are closer to Jupiter and the scattered light from the planet is tremendous," Sheppard told Sky and Telescope. The light reflected by Jupiter obscures these moons, so by 2000 astronomers...
