AFTERWORD

The Stars, Like Dust was written and first published in 1950. At that time, we did not know as much about planetary atmospheres as we do now. In Chapter 17, I speak of a lifeless world as possessing nitrogen and oxygen, but no carbon dioxide. It seems now quite certain that a lifeless “E-type” world (a small and rocky one, like Earth, that is relatively close to its star) would, if it possessed an atmosphere, have one that was made up of nitrogen and carbon dioxide, but no oxygen.

I can’t change Chapter 17 appropriately without having to rewrite a great deal of the book, so I will ask you to suspend your disbelief in this respect and enjoy the book (assuming you do) on its own terms.
