The mistake previous researchers made , therefore , was thinking of the methylated amino acids of meteorites as ingredients of life .
所以，此前的研究者错误的认为陨星中的甲基化氨基酸就是生命的成分。
Analysis of the chemistry of metallic meteorites suggests they come from more than 60 different small planets that have broken up over the solar system 's history .
对金属陨星的化学分析表明，它们来自太阳系历史上破碎的60多个不同的小行星。
These have been associated with iron meteorites , are usually reddish and thought to be fragments of the cores of much larger objects .
