bbc英语听力练习：新行星中的外星球Eight new planets 新行星中的“外星球”
天文学家说在遥远的太阳系外最新发现的八颗新行星中的一颗是“最类似地球的外星球”。

这八颗类地行星是由美国国家航空航天局（NASA）的开普勒太空望远镜所探测出的。

此探测结果是在美国天文
学会的一次会议上公布的。

以下是 BBC 记者 Jonathan Webb 的报道：
Spotting ‘Alien Earths’ is the reason the Kepler spacecraft was launched six years ago. It looks deep into space for tell-tale dips in the brightness of faraway stars.
Eight new so-called exoplanets were revealed here, taking Kepler’s overall tally1 to more than 1,000. But only very
few planets from that total are thought to be Earth-like and habitable, sitting in a temperate2 Goldilocks zone around
their various suns.
One of the new arrivals, called Kepler 438b, is the most like our home that astronomers3 have ever seen： just 12% bigger than Earth and 40% warmer.
They say if we could stand on its surface, nearly 500
light years away, the sky would be red because of the dwarf4 star it has for a sun.
