692. 实验室里的宇宙尘埃：探寻生命起源
from 知为谁 · host 知为谁
悉尼大学的博士生 Linda Losurdo 成功在实验室中人工合成了宇宙尘埃，这一突破性成果旨在揭示生命起源的奥秘。通过向玻璃管内的混合气体施加高压电流，研究人员模拟了恒星周边极端的物理环境，从而产生了少量的颗粒样本。这种实验室制造的模拟物让科学家能够避开外太空采样难题，直接研究有机分子在恒星际空间的演化过程。该项研究不仅证明了生命的化学基石在宇宙中可能普遍存在，也为探索地球生命究竟是本土产生还是源于深空提供了关键线索。通过构建不同环境下的尘埃数据库，这项技术有望帮助人类精准还原太阳系形成之前的原始化学历史。内容来源：https://www.cnn.com/2026/02/06/science/cosmic-dust-discovery-life-beginnings
