When searching for extraterrestrial life, and particularly intelligent life, elsewhere in the solar system or in our galaxy, the obvious places to look are habitable Earth-like planets. This is because most living organisms are quite vulnerable to harsh conditions, and thus the presence of life ...
Each of the planets could be suitable for life.The system's host star, called TRAPPIST - 1, is what is known as an ultracool dwarf. It is not a very large star, just a little bit bigger than Jupiter.The system is one of the closest star and planet systems known to us. The star ...
During the evolution of the universe, newly formed stars have progressively become more metal-rich, exposing organisms to increasingly intense ultraviolet radiation. Our findings imply that planets hosted by stars with low metallicity are the best targets to search for complex life on land....
What makes the Earth more suitable for life than other planets in the solar system? A. The Earth is the only planet that can receive energy from the sun. B. The sun is at the right distance from us and in proper size. C. The distance between the planets is neither too long nor ...
A key component of determining whether exoplanets are suitable for human life is classifying climate conditions and measuring climate sensitivity. The latest study focused on TRAPPIST-1e, a planet that will be observed by the James Webb Space Telescope next year and is situated around 40 light yea...

"possible for life to exist on" 应搭配形式主语结构(如 "It is possible for life to exist on some of them"),选项B用 "some of which" 导致语法不当。 - **C**:表述模糊,“与地球情况相同”不准确(行星环境完全复制地球可能性极低),且未明确提及支持生命的关键因素(如液态水)。 综上,D选项在...
Researchers believe that at least three of the planets could be suitable for life because of their size and proximity to their star. The red star, named TRAPPIST-1, is half the of the Sun and only of its mass. Researchers discovered the planets after small shadows interrupting TRAPPIST-1’...
3. 从“A planet that is neither too hot nor too cold to sustain liquid water on its surface is generally considered to have the potential for life.” 可知,生命最重要的元素是液态水,B 正确。 4. 从“The reason is probably because no one was looking, de Wit said.” 可知,没发现绕超冷...
Is the Earth the right model and the only universal key to understand habitability, the origin and maintenance of life? Are we able to detect life elsewhere ...
