宇宙尘比想象中的多孔多, 影响分子在空间的形成, 但科学家们却争论其稳定性。 Cosmic dust is more porous than thought, affecting how molecules form in space, but scientists debate its stability.

根据Heriot-Watt大学和Friedrich Schiller大学哲纳大学研究人员领导的一项研究,对恒星和行星形成至关重要的宇宙尘比以前想象的多孔多、海绵多。 Cosmic dust, essential to star and planet formation, is more porous and spongy than previously thought, according to a study led by researchers from Heriot-Watt University and Friedrich Schiller University Jena. 该研究在《天文学和天体物理学评论》中发表。 研究表明,根据欧洲航天局罗塞塔飞行任务的数据,星际灰尘颗粒不象岩石一样固态,而类似于浮绵、空填海绵,孔隙超过99%。 Published in Astronomy and Astrophysics Review, the research indicates that interstellar dust grains are not solid like rocks but resemble fluffy, void-filled sponges with porosities exceeding 99%, based on data from the European Space Agency’s Rosetta mission. 这种高孔隙性大大提高了化学反应的表面积,有可能改变对空间分子形成的理解。 This high porosity greatly increases surface area for chemical reactions, potentially altering understanding of molecular formation in space. 然而,对调查结果进行了辩论,因为一些模型表明,这些脆弱的谷物可能太冷,或容易销毁,无法与观测到的星际条件相匹配。 However, the findings are debated, as some models suggest such fragile grains may be too cold or easily destroyed to match observed interstellar conditions. 科学家一致认为需要进行进一步研究,以解决不确定性。 Scientists agree further research is needed to resolve the uncertainty.
