The Magellanic Clouds, the closest undisrupted neighboring dwarf galaxies to our own, show an energetic star formation activity, demonstrated by their bright ionized nebulae. Such HII regions, being close to us, are ideal laboratories for a comprehensive study of star formation in environments similar to that of the early universe due to their low metal abundances. We wish to employ ATCA for the construction of a detailed high-resolution radio map of the region NGC 602/N 90 in the Small Magellanic Cloud. We found evidence that the young stellar association NGC 602, centered on the ring-shaped HII region N 90, has triggered star formation on its ridge. This process has been revealed by at least 17 candidate YSOs, which are identified with Spitzer Space Telescope on the edge of the emission nebula. The proposed observations will reveal the morphology of the ionizing process, allowing us to estimate the total energy input in the region, and identify highly embedded massive protostellar objects via their radio continuum emission. Consequently, these data will allow us for the first time to compare thoroughly an exceptional SMC HII region with similar ones already observed in the Milky Way.
