Abstract
With its peculiar appearance, I Zw 18 has long been considered a unique example of a young galaxy in the nearby Universe. In this paper, we summarize the observational history of this famous galaxy, discuss the controversies surrounding its evolutionary state, and present new insights gained from JWST/NIRCam observations. These recent findings shed light on one of the most intriguing mysteries in extragalactic astronomy.Keywords
