NGC 6357 - War and Peace Nebula in Scorpius

Roiling maelstrom of gas and dust clouds in the heart of the War and Peace nebula in Scorpius.

While the light from our sun takes around 8 minutes to reach us, this nebula is around 8000 light years distant.
The 2 brightest stars in this image are very much in the foreground, being only 248 and 330 light years distant, or only 4% of the distance from earth to the nebula in the background.

The nebula holds a vast tapestry of gas, dark dust and newly birthed stars wreathed in cocoons of gas and dust from which they nucleated and ignited their nuclear furnaces. Energetic radiation and interstellar winds of solar particles emitted by these hot young stars have sculpted intricate shapes into the nebula. Dusty pillars of molecular gas hide massive proto-stars that are embedded throughout the pillars.

The wonder of creation - of new stars and planetary systems - ongoing before our very eyes.

Imaged from Seacliff, Adelaide with narrowband filters over the course of 3 imaging sessions (28 June, 6 July, 7 July), and involving 9 hours of light capture via 1080 x 30 second sub-frames (Skywatcher 8 inch/f5 Newtonian.

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.
