After reading up on this object I wanted to bring it out as smouldering coals, ready to burst apart and blaze into flame. Its a H2 area of a giant molecular cloud with embedded young giant O and B stars radiating in everything up to Xray. It is illuminated by a star cluster of 2000 stars (31 are O or B, the workhorses when it comes to emission nebulae) and xray studies show it has embedded in it another 200 stars detectable by their xray radiation (https://apod.nasa.gov/apod/ap050108.html). In the technical description there are 2 water masers so there are interesting particle and magnetic things happening. - microwave lasers that can be detected 5000-6000 light years away! (Actually they're surprising common around massive stars and are a marker of active star formation, which just goes to increase RCW 38's cred as a cauldron of star formation) And they say the star cluster is less than a million years old.

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.
