閱讀下面的短文，選擇正確答案。

The search for life outside the Earth may have moved to a new and exciting level．A team of astronomers （天文學家） said they have found a new planet that has many important parts similar to those of the Earth.

The planet，which travels around a red dwarf star （紅矮星） called Gliese 581，has the right size and temperature．Most importantly，the planet lies in the suitable living area of the star，which makes the planet not too hot or too cold．

Scientists say the new world，Gliese 581 c，is five times larger than the Earth．It may have water since it is in the right place from the red dwarf．

Swiss scientist Michel Mayor said it is an important step on the way to find possible life in the space and there are still lots of questions．

For more than ten years，astronomers and scientists have been keeping their eyes on the space in search for another Earth，another world that can support life or already has it．

According to records，the first discovery of extra solar planet going around a normal star was made in 1995．Since then，the number of newly discovered worlds has increased to about 200．But they are just dead with lifeless bodies.

The Gliese 581 c came into our eyes and mankind has reason to celebrate．After all，we may have living neighbours．The discovery doesn't promise much，but it offers hope that there could be other people or living things out there.

參考譯文

對地球外生命的探索可能已經(jīng)進入了一個嶄新并令人興奮的階段。一支天文科學家研究小組說，他們已經(jīng)發(fā)現(xiàn)了一顆新的行星，它的許多重要組成部分與地球相似。

這個行星圍繞著一顆名為“格利澤581”的紅矮星運轉(zhuǎn)，它有著適合生命存在的體積和溫度。最重要的是，這顆行星位于紅矮星的適居帶內(nèi)，這樣它的表面溫度既不會太熱也不會太冷。

科學家說，這個新世界——格利澤581 c有地球體積的5倍大。由于它距離紅矮星位置適中，因此上面可能存在水分。

瑞士科學家米歇爾·梅厄說，這是人類探索太空生命過程中邁出的重要一步，當然仍有許多問題等待解決。

十多年來，天文學家和科學家一直在觀測太空，以尋找另一個“地球”，一個適合生命生存或已有生命存在的世界。

據(jù)相關(guān)記載，人類第一次發(fā)現(xiàn)圍繞正常恒星運轉(zhuǎn)的太陽系外的行星是在1995年。此后新發(fā)現(xiàn)的行星數(shù)量已增至約200顆。但這些行星都是無生命跡象的寂寞天體。

所以，這次格利澤581 c進入我們的視野，人們有理由慶祝。畢竟，我們可能有活著的鄰居，雖然這次發(fā)現(xiàn)的前景并不很明朗，但它給了我們希望：地球以外可能有其他文明或生命存在。
