英文原文

In the realm of obscure scientific disciplines, astrobiology stands out as a fascinating field that bridges the gap between astronomy and biology. It explores the possibility of life beyond Earth, delving into the question of whether life exists or could exist on other planets or moons in our universe.

在鲜为人知的科学领域中，天体生物学作为一个迷人的领域脱颖而出，它架起了天文学与生物学之间的桥梁。该领域探索了地球之外生命存在的可能性，深入研究了我们宇宙中其他行星或卫星上是否存在生命或生命能否存在的问题。

One of the key concepts in astrobiology is the "habitable zone," referring to the region around a star where conditions are just right for liquid water to exist on a planet's surface. This is crucial as water is considered the cornerstone for the development of life as we know it.

天体生物学中的一个关键概念是“宜居带”，它指的是围绕恒星的一个区域，该区域的条件正好适合液态水在行星表面存在。这一点至关重要，因为水被认为是我们所知生命发展的基石。

Scientists have identified several potential habitable exoplanets, including those orbiting the TRAPPIST-1 system, a star located about 40 light-years from Earth. These planets, despite their extreme proximity to each other, exhibit varying degrees of atmospheric conditions that could potentially support life.

科学家们已经发现了几个潜在的宜居系外行星，包括围绕TRAPPIST-1系统运行的行星，该系统距离地球约40光年。尽管这些行星彼此间距离极近，但它们却展现出不同程度的大气条件，这些条件可能支持生命的存在。

However, the search for extraterrestrial life is fraught with challenges. One of the biggest hurdles is the vast distances involved, making it incredibly difficult and expensive to send probes or spacecraft to these distant worlds. Furthermore, the detection of life signatures, such as biosignatures in a planet's atmosphere, requires highly specialized and sensitive instruments.

然而，寻找外星生命的道路充满了挑战。其中最大的障碍之一是所涉及的巨大距离，这使得向这些遥远的世界发送探测器或航天器变得极其困难和昂贵。此外，检测生命迹象，如行星大气中的生物特征，需要高度专业化和灵敏的仪器。

Despite these obstacles, the pursuit of astrobiology remains a compelling endeavor, driven by the innate human curiosity to explore the unknown. It promises to revolutionize our understanding of the universe and our place within it, potentially answering one of the most profound questions of all: Are we alone in the cosmos?

尽管存在这些障碍，但天体生物学的追求仍然是一项引人入胜的事业，它源自人类探索未知的固有好奇心。天体生物学有望彻底改变我们对宇宙及其内在位置的理解，并可能回答所有问题中最深刻的一个：我们在宇宙中是否孤独？

答案解析

1.答案：B

解析：文章中明确提到天体生物学探索的是地球之外生命存在的可能性，即探索地球以外的生命。因此，天体生物学的主要焦点是探索地球以外的生命。

2.答案：B

解析：文章定义“宜居带”为围绕恒星的一个区域，该区域的条件正好适合液态水在行星表面存在。这是天体生物学中一个重要的概念，因为它与生命存在的可能性直接相关。

3.答案：B

解析：文章提到TRAPPIST-1系统围绕其运行的行星中有几个可能是宜居的系外行星。这是TRAPPIST-1在天体生物学研究中的一个重要特点，使得它成为该领域研究的重点对象。

4.答案：B

解析：文章指出，寻找外星生命的道路充满了挑战，其中之一就是检测生命迹象，如行星大气中的生物特征，这需要高度专业化和灵敏的仪器。这直接表明了检测生物特征是寻找外星生命过程中的一个主要挑战。
