NGC 6334 is a souther-sky “Star-Burst” cluster in our own galaxy. It lies about 5,500 light-years from us in the direction of the galactic center and nearly in the galactic plane. The cluster itself inhabits the redish cloud in the upper right of this image. The term “star-birst region” denotes a region where exceptional rapid star formation has arisen. In this case the triggering event for the star-burst may have been the collision between two giant molecular clouds (Fukui, et al. 2018).

The stars young and massive in NGC 6334 emit winds that rake the HII parent cloud, sculpting the dust and gas into streaks, loops, and bubbles. However, Hua-bai Li and colleagues (2015) found relationships between the magnetic fields in NGC 6334 and filiment structures in the cloud strures, suggesting that the cloud may be too young to have yet been effected by the winds from the young stars, which should dominate. Or, maybe as Wade (2014) suggests, the magnetic fields of the O stars themselves may direct the paths of their stellar winds.

The cloud stands apart from other clouds hosting star-burst activities in that it has the most intense emissions from ammonia known for any such cloud (Kuiper, et al. 1995). Taken together, the magnetic-lines controling structres and the presence o ammonial, The cloud and star-burst ages appear to be quite young, perhaps only about a million years old.

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.
