NGC 6357, The Lobster Nebula (Ruben Barbosa)

NGC 6357, The Lobster Nebula

* Image acquisition by: iTelescope-Portugal.

* Processing: Ruben Barbosa.

The Lobster Nebula is located in the Constellation of the Scorpion, is approximately 60 minutes in diameter and consists of HII regions, high mass stars (O and B), photodiodes regions and infrared sources.

The elegant structures it exhibits, result from interactions between stellar winds, magnetic fields, radiation pressure and gravity, and the brightness resulting from the emission of ionized hydrogen.

The central, bubble-like region is separated by a column of dust that divides the region into two wells and exhibits diffuse emissions of OIII revealing that it is filled by hot gas (10^4 K), with the agglomerate Pismis 24 being the main source of excitation in this region.

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.
