NGC 346 Cluster associated with nebulosity in Tucana
The brightest star-forming region in the neighbouring Small Magellanic Cloud galaxy, The light, wind and heat given off by massive stars have dispersed the glowing gas within and around this star cluster, forming a surrounding wispy nebular structure that looks like a cobweb.

Clusters NGC 419 and NGC 416 are located in the 'Wing' of the SMC, and represent two of the brightest and richest members of the SMC. The present investigation is concerned with the construction of color-magnitude diagrams (CMDs) for both clusters. The CMDs are analysed, taking into account the global features, a photometric estimate of the cluster metallicities, and the ages and the distance-reddening problem. It is found that NGC 416 is about 1.5 Gyr older than NGC 419. The clusters' absolute ages are 2.5 + or - 0.7 Gyr and 1.2 + or - 0.5 Gyr, respectively. Integrated photometry is feasible to very low apparent magnitudes, and, for this reason, any calibration of integrated photometric indices versus age and/or metallicity, which can be performed in the Magellanic Clouds, is of fundamental importance in the study of more distant unresolved galaxies.


The globular star cluster NGC 419 in the Small Magellanic Cloud, in the constellation Tucana, has a diameter of 2.4' and an apparent magnitude of +10.00 mag.
The globular cluster NGC 419 was discovered on the 2 September 1826 by the Scottish astronomer James Dunlop.
