N66 & NGC346, the Hii regions & Clusters of the SMC in Ha

The Small Magellanic Cloud (SMC) is a companion galaxy of the Milky Way, located about 197,000 light years from Earth in the southern constellation of Tucana. The SMC has evolved slowly and preserved many of the characteristics expected of ‘young’ galaxies, and galaxies in the early universe. These include low metallicity, high gas content and a lack of organized rotation.

N66 is the largest Hii region in the SMC. It is excited by radiation from stars in the open cluster NGC346, together forming the largest star formation region in the SMC. NGC346 is extremely young (~3 million years), and its excitation generates an H-alpha luminosity about 60 times brighter than the Orion Nebula in N66.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
