Letters are usually comments on recent articles. Articles are usually solicited for magazines like Scientific American, Discover, and National Geographic, and must pass a stringent peer-review system for actual journals. Even the popular magazines won't just publish anything. But you can always send (short) letters and you might get one published.Where can I publish popular science articles as letters to editors or guest editorials?
if you write an ARTICLE, they won;t select it for publication as a LEtter to the Editor.



A LETTER must be short ands sweet, and does not give you enough space to develop a 'real" scientific Idea.



ALL of the POPULAR science journals want REAL science, made simple for the "Populace" (general readership). You can;t just go in with any BS idea, and expect to get published.



So go to a good book store, pick a magazine that covers the kind of science you want to write about, look in the magazine, and see how and where to make submissions.
