根据新研究，地球可能正在金星上播下生命的种子
模型表明，从地球撞击抛出的物质可能到达金星云层，并可能在那里短暂生存。有生源说认为生命或生命所需的成分可以在小行星、彗星和其他物体上穿越太空。如果生命的组成部分出现在一颗行星上，强大的撞击可能会将其表面的物质炸飞[...]
来源:SciTech日报Models suggest that impact-ejected material from Earth could reachVenus’ clouds and potentially survive there briefly.
Panspermia is the idea that life, or the ingredients needed for life, can move through space on asteroids, comets, and other objects.如果生命的组成部分出现在一颗行星上，强大的撞击可能会将其表面的物质炸入太空，并将其送往另一个世界。
For decades, researchers have discussed whether this kind of exchange might have happened between Earth and Mars (in both directions).最近，关于金星厚云层中可能存在微生物的争论重新引发了人们对物质是否也可以在金星、地球和火星之间移动的兴趣。
A recent study presented at the 2026 Lunar and Planetary Science Conference (LPSC) examined that possibility in detail. The work was carried out by a team from The Johns Hopkins University Applied Physics Laboratory (JHUAPL) and Sandia National Laboratories. Using the “Venus Life Equation” (VLE), a framework developed by Noam Izenberg et al. 2021 年，研究人员模拟了从地球发射的物质是否能让生命在金星云层中生存至少每个世纪几天。
A framework weighs Venus life
与德雷克方程一样，VLE 通过将问题分解为几个相乘的因素来估计生命的机会。 In mathematical form, the VLE is written as follows:### L = O x R x C
其中L是现存生命的可能性（0到1，其中0是没有机会，1是确定性），O是起源（生命在金星上开始并建立的机会），R是鲁棒性（生物圈存在并承受变化的潜力），C是连续性（宜居条件持续到今天的机会）。 Using this framework, the team first considered how any organic material, regardless of its origin, must survive the journey through space.
