剧情介绍
Join astronomers in a race to find a planet that can sustain life. Amid all the space in the universe, is there another world like ours?
Astronomers studying a nearby star say they've found the first potentially habitable planet—likely a rocky place with an atmosphere, temperate regions, and crucially, liquid water, considered vital for life as we know it. Other extrasolar planets have been called Earthlike, but, astronomer Paul Butler assured, "this is really the first Goldilocks planet"—not too hot, not too cold.

不懈的努力值得肯定,通俗易懂,即便不学天体物理学,也能窥一隅科学家的思路。

敘述混亂,一會兒講幾架望遠鏡之間的競爭,一會兒又穿插到對類地行星環境的想像與模擬,都沒有講好。不過學到兩個尋找行星的思路:一是找凌日現象,即恆星有規律變暗;而是從恆星光譜的隙縫中發現開普勒效應,即恆星的震蕩。

寻找第二个地球,其实就是搜寻地球外的生命。生命所忍受的环境要比想象中的残酷的多,所以宇宙出现生命的概率就越大。我们已经寻找到了不少类地行星,看来不久的将来发现新的孕育生命的星球已经不再遥远,我们期待那一天。
