We present a case for the exploration of Venus as an astrobiology target-(1) investigations focused on the likelihood that liquid water existed on the surface in the past, leading to the potential for the origin and evolution of life, (2) investigations into the potential for habitable zones within Venus' present-day clouds and Venus-like exo atmospheres, (3) theoretical investigations into how active aerobiology may impact the radiative energy balance of Venus' clouds and Venus-like atmospheres, and (4) application of these investigative approaches toward better understanding the atmospheric dynamics and habitability of exoplanets. The proximity of Venus to Earth, guidance for exoplanet habitability investigations, and access to the potential cloud habitable layer and surface for prolonged extended measurements together make the planet a very attractive target for near term astrobiological exploration.
我们提出了探索金星作为天体生物学目标的理由-(1) 重点研究过去金星表面是否存在液态水的可能性，这可能导致生命的起源和演化，(2) 研究金星当前云层和类金星外大气层中潜在的宜居区域，(3) 理论上研究活跃的空气生物学如何影响金星云层和类金星大气层的辐射能量平衡，以及(4) 将这些研究方法应用于更好地了解系外行星的大气动力学和可居住性。金星与地球的距离很近，为系外行星可居住性研究提供了指导，并且可以进入潜在的云层宜居层和表面进行长时间的扩展测量，这使得金星成为近期天体生物学探索的一个极具吸引力的目标。
