Many people have heard the popular catchphrase "We are made of stardust". Indeed, in a truly cosmic lifecycle, stars, planets and their inhabitants are born from the ashes of stars that have long gone, but whose existence is evidenced by our very own chemical composition. Indeed, we now know that all elements like carbon and oxygen are produced in the interior of stars. Exactly how this stardust is formed however, and what its exact chemical composition is, is not well known.

很多人都听过一句流行的口号：“我们是由星尘组成的”。事实上，在一个真正的宇宙生命周期中，恒星、行星和它们的居民都是从早已逝去的恒星的灰烬中诞生的，但我们自己的化学成分证明了它们的存在。事实上，我们现在知道，所有的元素，如碳和氧，都是在恒星内部产生的。然而，这颗星尘究竟是如何形成的，以及它的确切化学成分是什么，目前还不清楚。
