气体巨星

gas giant───气体巨星；主要由气体组成的巨行星，如木星、土星、天王星和海王星

gas plants───天然气厂

gas lights───煤气灯

gas plant───煤气厂，[油气]天然气加工厂；煤气发生装置

gas rings───n.煤气灶火圈；环形轻便燃气炉

gas tanks───煤气筒，煤气罐；汽车之油箱

red giants───n.[天]红巨星

blue giants───蓝巨星

gas engines───内燃机；燃气发动机

Then come the gas giants, Jupiter and Saturn.───之后是气态巨星，木星和土星。

Those are the gas giants, the four heavyweights of the solar system.───这些都是气体行星，太阳系的四个重量级。

Jupiter, Saturn, Uranus, and Neptune. Those are the gas giants, the four heavyweights of the solar system. But was there once a fifth?───木星、土星、天王星和海王星。这些都是气体行星，是太阳系的四个重量级。但曾经存在第五个行星吗？

Spitzer, meanwhile, found a surprisinglack of water in the atmospheres of two other gas giants.───同时，斯比哲太空望远镜发现另外两颗气态行星的大气层极度缺水。

they're both gas giants and yet Saturn has less sunlight to power the winds, and winds are stronger.───他们都是气体巨星，但土星较少的阳光可以影响风势，所以风力更强劲。

After 10 billion years of cooling, large gas giants are all very nearly Jupiter's radius, but more massive objects are slightly smaller.───在冷却了一百亿年后，大型气态巨行星的半径将非常近似于木星，但质量越高，半径却会略微缩小。

It could be that the planet managed to cling onto a moon when all the other gas giants in our solar system had already lost theirs.───可能是因为在我们太阳系的其他气态巨星已经失去自己的卫星的时候土星捕获了一个月亮。

At this point, the solar system is composed only of solid, protoplanetary bodies and gas giants.───在这点上，太阳系仅仅是由固体、原行星和巨型气体行星组成的。

Most famous of the gas giants is Jupiter, which also benefited from the vigilant observation of an amateur astronomer this week.───最有名的气态巨行星就是木星，它也于本周受惠于一名业余天文爱好者警觉的观察。

If the Sun was a basketball the gas giants Jupiter and Saturn would be the size of grapefruits, and the Earth would be, on that scale, the size of a peppercorn.

For instance, some systems could house only Earthlike planets and no gas giants, Gould said.

And since HD 209458b is a pretty typical "hot Jupiter"—the nickname for close-orbiting gas giants—it's "almost certain" that all hot Jupiters have comet-like tails, Linsky said.

Scientists have found many planets like HD 209458 b – huge gas giants that orbit hazardously close to their stars and have hellishly hot, poisonous atmospheres.
