The Sun is rich in helium, as are the solar system’s gas giant planets.───太阳作为太阳系中的气体巨行星，氦含量丰富。
Moving on through the asteroid belt we enter the realms of the gas giant planets: Jupiter, Saturn, Uranus, and Neptune, all of which dwarf the Earth.───穿过小行星带继续前进，我们进入了气体巨行星区域：木星、土星、天王星、海王星，所有这些都使地球看起来像个侏儒。
The name originates from the 18th century, when telescopes weren't powerful enough to distinguish nebulae from gas giant planets.───这个名字源于18世纪，当时望远镜威力还不够强大，无法区分星云和气态巨行星。
Giant planets far from the Sun have material nearby that condenses, or collects, into satellites.───离太阳比较远的大型行星，其附近的物质容易凝聚成卫星。
That's not the case on some of the solar system's other heavenly bodies, specifically the moons which orbit large gas giant planets.───该现象并非是针对太阳系而言的个别现象而是就所有天体而言的普遍现象，特别是针对星球表面大气层厚重的卫星。
Today, direct detection of the visible and infrared light from giant planets in wide orbits is becoming increasingly possible.───今天，从广泛的巨行星轨道可见光和红外光的直接检测正变得越来越可能。
That's because planets bound to a parent star would only reflect the survivors, not how many gas giant planets actually formed.───目前与恒星相伴的行星都是那场角力中的幸存者，并不能说明实际上有多少气态巨行星形成。
In fact, distance from the sun determined that close-in bodies became small rocky planets and farther ones became giant planets rich in volatile ices and gases.
The giant planets will remain a puzzle for a long time.
Astronomers have looked for the presence of giant planets in the habitable zone of Alpha Centauri, the nearby star system that is home to Pandora in the film, and have not found one.
The giant planets, with such feeble solar heating, are also very cold.
The high abundances of hydrogen and helium are features of the giant planets also.
The giant planets are, in fact, warm inside.
But that betrays a terribly parochial notion of what giant planets are like.
Typically, the giant planets contain about forty-five parts per million of helium-3 in their atmospheres.
The research is based on surveys of stars with gas giant planets—similar to Jupiter and Saturn—that orbit far from their stars.
