NASA’s planet-hunting telescope has found 10 new planets outside our solar system that are likely the right size and temperature to potentially have life on them.

After four years of searching, the Kepler telescope has detected a total of 49 planets in the Goldilocks zone. And it only looked in a tiny part of the galaxy, one quarter of one percent of a galaxy that holds about 200 billion stars.

Seven of the 10 newfound Earth-size planets circle stars that are just like ours. That means the planets may have some of the most basic requirements that life needs, upping the chances for life.

“Are we alone? Maybe Kepler today has told us indirectly, although we need confirmation, that we are probably not alone,’’ Kepler scientist Mario Perez said in a news conference on June 19.

The Kepler space telescope was launched in 2009 with the aim of surveying part of the galaxy to see how frequent Earth-size and potentially habitable planets are.(AP)

美國太空總署近日透過專門搜索新星球的克卜勒太空望遠鏡發現了十顆類似地球的系外行星,不僅大小與溫度都接近地球,還可能有生物存在。

經過四年的搜尋,克卜勒太空望遠鏡在宜居帶總共發現四十九顆行星。整個銀河系估計約有兩千億顆星球,而目前美國太空總署以克卜勒太空望遠鏡調查過的區域只有其中的百分之零點二五。

在最新發現的十顆類地行星中,有七顆繞著恆星運行。這表示這些行星可能具備能孕育生命的基本條件,可能有生物存在。

參與克卜勒任務的科學家馬力歐·佩瑞斯在上個月十九日的記者會上說:「宇宙中還有其他的生命嗎?雖然現在還無法證實,但或許克卜勒的新發現已經間接告訴我們,在地球之外是有其他生物的。」
