Journals consist mostly of articles written by scholars and researchers, reporting in detail on their original research, and "peer reviewed" by other experts before they’re published. Most are published by professional or academic organizations, for specialists in that field.
Journals are published regularly, like magazines, but most magazine articles provide more basic information, and are written for average people (or maybe fans and hobbyists).
