Cosmic dust contains all the elements needed for life but has previously been considered too rare to have acted as a ‘fertilizer’ for prebiotic chemistry. Now, using a combination of astrophysical and geological models, it is revealed that cosmic dust could have gently accumulated on the surface of early Earth in sufficient quantities to promote the chemical reactions that led to first life.

宇宙尘埃可能驱动了地球上生命的地球化学起源

宇宙尘埃含有生命所需的所有元素，但此前被认为太稀有，无法充当生命起源化学的“肥料”。现在，结合天体物理和地质模型，人们发现宇宙尘埃可能在早期地球表面轻轻积累，数量足以促进导致第一个生命诞生的化学反应。
