Abstract : The Carina Nebula is a star-forming region well-known for its extreme massive stellar content and ongoing star-formation activity. IRAS 10427-6032 is known to be a possible H II region that lies in the direction of the Carina Nebula. We study this region using various archival data including near-IR (VISTA Carina Nebula Survey), mid-IR (Spitzer, WISE), far-IR (AKARI, Herschel), radio (MGPS), and sub-mm (ATLASGAL). We discover here a young (~1-2 Myr) embedded star-cluster that constitutes a proof of ongoing star-formation in the extreme outskirts of the Nebula. In particular, we find ~40 Class II YSO candidates, and 6-7 Class I YSO candidates using the near and mid-IR data. The radio continuum image at 843 MHz (MGPS) shows the presence of a compact H II region. Lyman continuum luminosity calculation indicates the spectral type of the ionizing source to be earlier than B0-B0.5. In addition to this compact H II region, the embedded cluster shows the presence of a cool dense clump detected by ATLASGAL that sits adjacent to it, and the YSO candidates which are found both within the core and in the peripheral regions.
