过去和现在的胚种论：空间生命传播的天体物理和生物物理条件
Panspermia, Past and Present: Astrophysical and Biophysical Conditions for the Dissemination of Life in Space
摘要：
从天文学上讲，有可行的机制将有机物质分布在整个银河系中。从生物学上讲，紫外线和宇宙射线的破坏性影响意味着大多数生物在到达新世界时都已破碎和死亡。因此，传统形式的胚种论的可能性必须被认为是低的。然而，受损的生物分子的信息内容可能有助于播种新的生命（necropanspermia）。
英文摘要：
Astronomically, there are viable mechanisms for distributing organic material throughout the Milky Way. Biologically, the destructive effects of ultraviolet light and cosmic rays means that the majority of organisms arrive broken and dead on a new world. The likelihood of conventional forms of panspermia must therefore be considered low. However, the information content of dam-aged biological molecules might serve to seed new life (necropanspermia).
