但后来当那些恒星掩星揭示了冥王星出人意料的大气层后，我就迷上了这方面的研究。

But after those stellar occultations revealed its unexpected atmosphere, I was hooked on Pluto atmosphere research.

当时，人们用望远镜观察比冥王星更远的星体(被称为恒星掩星)时发现冥王星存在甲烷大气层，而且可能正在快速向宇宙空间流失。

That's when telescope observations of distant stars going behind Pluto (known as stellar occultations) showed that it had a methane atmosphere, probably rapidly evaporating to space.
