A Guide to Make an Earth-like Planet

文 译/ 两袖清风 绘/ 马豆子

How do you make an Earthlike planet? The Harvard-Smithsonian Center'for Astrophysics(CfA) astronomers created a recipe for how you could "bake"your very own Earthlike model world.

Blend well in a large bowl,shape into a round ball with your hands and place it neatly in a habitable zone area around a young star. Do not over mix. Heat until mixture becomes a white hot glowing ball.Bake for a few million years.Cool until color changes from white to yellow to red and a golden— brown crust forms. It should not give off light anymore.Season with a dash of water and organic compounds. It will shrink a bit as steam escapes and clouds and oceans form. Stand back and wait a few more million years to see what happens. If you are lucky,a thin frosting of life may appear on the surface of your new world.

你会如何来制作一颗类地行星?美国哈佛- 史密森天体物理中心的天文学家们只做了一个配方,教你“焙制”个人专属的类地行星模型。

如何焙制将上述配料倒入一个大碗搅匀( 不要搅拌过头),然后用手将其捏成一个圆球,干净利落地将其置于某一年轻恒星附近的宜居区域。接着将这一混合而成的圆球加热至白热发光状态,再烘烤几百万年。随后进行冷却处理,直至球体颜色由白转黄。最后变红,并形成一层金褐色的外壳,此时球体应不再发光才对。接下来,添加少许水和有机化合物。随着蒸汽蒸发,云层和海洋形成,球体将会略微缩小。此时退到一旁,等待几百万年,静观其变。幸运的话,在你创造的这个新世界的地表上可能会出现一层稀疏的生命迹象。
