在太阳系历史的早期，后来凝聚成行星的物质曾被大量的紫外线照射，这可以解释这种差异。它是从哪里来的？出现了两种理论。紫外线要么来自我们当时年轻的太阳，要么来自太阳的恒星“苗圃”中的一颗附近的大恒星。现在，来自圣路易斯华盛顿大学文理学院物理学助理教授Ryan Ogliore实验室的研究人员，已经确定了哪种情况是造成这种“分裂”的原因：很可能是来自一颗早已死亡的大质量恒星的光，在太阳系的岩石体上留下了这个印象。这项研究由物理系空间科学实验室的博士后研究助理Lionel Vacher领导。他们的研究结果发表在《Geochimica et Cosmochimica Acta》杂志上。 Ogliore说：“我们知道我们是从星尘中诞生的：也就是说，由我们银河系附近的其他恒星产生的尘埃是太阳系的组成部分。但这项研究表明，星光对我们的起源也有深刻的影响。�
