  We introduce \emph{Astronomy and Computing}, a new journal for the growing
population of people working in the domain where astronomy overlaps with
computer science and information technology. The journal aims to provide a new
communication channel within that community, which is not well served by
current journals, and to help secure recognition of its true importance within
modern astronomy. In this inaugural editorial, we describe the rationale for
creating the journal, outline its scope and ambitions, and seek input from the
community in defining in detail how the journal should work towards its
high-level goals.
