NGC 6357, Lobster Nebula

Near the Cat's Paw nebula (NGC 6334), the Lobster Nebula is 5.5K-6.0K light-years distant in Scorpius. The field is ~1.5 x 1.0 degree. This implies the region is roughly 160 light-years by 100 light-years wide.

Beyond the obvious dust/gas and star forming region, the object contains a star cluster with 3 of the largest known stars. Originally thought to contain a single 300 stellar mass object, later (spectroscopic?) analysis revealed 3 separate objects, each of size 100 solar masses.

In this image, the framing didn't exactly turn out quite right, and a small portion of the bottom "claw" has been cut off (oops). I'll try to improve on this in the future. For now, let's consider this a work in progress.

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.
