The Kepler orbiting observatory was launched with a simple mission - to find other Earths. NASA describes it as 'a search for habitable planets.'
随着一项简单的任务,寻找其他“地球”,开普勒轨道天文台启动。美国宇航局将其描述为“一次对可居住的星球的搜寻”。
And analysis of its first 136 days of data has already begun - with scientists combing through scans of 150,000 stars, and evidence of 1,235 potential planets.
通过扫描浏览150,000颗恒星,科学家们已经开始分析梳理头136天的数据,结果表明有1,235颗可能的行星。
Such information is fascinating in itself - but it also allows scientists to work out projections using statistical analysis.
这类消息本身很吸引人的,但同时也需要科学家们运用数据分析得出推测。
One analysis has predicted that one-third of 'sun-like' stars - stars with the classification F, G or K - will have planets similar to Earth.
一项分析推测,三分之一的类太阳恒星,即F, G 或 K类恒星,将会有类似地球的行星存在。
Traub says, “About one-third of FGK stars are predicted to have at least one terrestrial, habitable-zone planet.”
Traub说:“根据预测,大约三分之一的F, G 或 K类类恒星会至少有一个行星类似地球,拥有可居住区域。”
Traub used statistical analysis to 'predict' planets that had not been detected by Kepler, and whether they would be within the 'habitable zone'. Traub's analysis hints that there may be even more potential 'Earths' orbiting them than previously thought - and that this 'principle' would extend to stars not yet scanned by Kepler.
