Cosmology is the study and understanding of existence in its totality, encompassing the infinite and eternal, and the origins and evolution of the cosmos, galaxies, stars, planets, earth, life, woman and man.

The interdisciplinary Journal of Cosmology is devoted to the study of "cosmology" and is dedicated to those men and women of rare genius and curiosity who wish to understand more and more about more and more: The study of existence in its totality.
Man, now I kind of feel bad about putting PLoS One on my list.
