That would give them a better sense of just how massive it is.
這將讓他們更好的感知這個物體有多么的巨大。
There maybe more to come. The two researchers think they have found a second promising target lurking in Kepler's data.
或許還能得到更多。兩位研究人員認為他們發現了隱藏在開普勒數據中的第二個有希望的目標。
And theory can offer a useful guide as to where else to look.
并且理論可以作為觀測的有效指導。
Many of the exoplanets discovered so far are so-called "hot Jupiters"—gas giants that orbit close to their stars (a configuration unknown in Earth's solar system).
目前所發現的很多系外行星都是所謂的“熱木星”，即氣態巨行星，繞它們的恒星的軌道而行（地球太陽系中的一種未知結構）。
Theorists believe such worlds must have formed farther out from their stars before being flung inward, perhaps by a close encounter with another planet.
理論學家認為這種世界一定是在被向內推進之前就在遙遠的恒星中成型了，或許是通過于另一個行星近距離接觸形成的。
That game of gravitational billiards would also strip any moons away from such a planet.
引力撞球的游戲也會讓衛星脫離該行星。
Better to look at "cool Jupiters"—those planets that, like Jupiter itself, orbit their stars at more sensible distances.
最好是看看“冷木星”—和木星本身一樣，那些行星會更近距離的圍繞著它們的恒星。
Only a handful of these are known from the Kepler data, says Dr Kipping, but "we'd like to use the Hubble to observe all of them, every time they transit."
開普勒數據中已知的僅有一小部分，基平博士表示，但“我們會利用哈博望遠鏡觀測所有，觀測它們每一次的移動?！?/div>
If everything goes according to plan, the study of exomoons may follow the pattern seen with exoplanets, where an initial trickle turns rapidly into a flood.
如果一切按計劃進行，系外行星的研究或許會遵循系外行星的模式—在這些系外行星上，最初的微妙移動迅速擴大。
A probe called the Transiting Exoplanet Survey Satellite (TESS) was launched in April.
一個名為凌日系外行星勘測衛星（TESS）的探測器于四月發射。
TESS is designed to observe stars much closer to Earth than those watched by Kepler.
TESS旨在觀測那些距離地球更近的恒星（與開普勒觀測到的相比）。
If it can observe for long enough, it may turn up more candidate exomoons.
如果TESS的觀測時間夠長，或許可以發現更多候選系外行星。
Follow-up observations of anything that TESS finds would be greatly aided by its comparative nearness.
對TESS所發現的任何物體的后續觀測都將受到其相對近距離的極大輔助。
And the Hubble is expected to be joined in 2020 by the budget-bustingly expensive, extremely late and very capable James Webb Space Telescope,
2020年，一種更加昂貴、先進且非常得力的詹姆斯·韋伯空間望遠鏡會加入哈博望遠鏡行列，
which will carry the largest mirror ever flown into space. The moons are out there. Finding them is only a matter of time.
前者載有最大的鏡面，比送入太空的任何一個都大。衛星就在那里，發現它們只是時間問題。
