Messier 17 or Omega Nebula

The Omega Nebula is designated Messier 17 and is sometimes called the Swan Nebula. It is located further south of the well-known Eagle Nebula (Messier 16) and is therefore a difficult target for those who want to image the nebula from the northern hemisphere.

The nebula is about 6'000 light years away from earth and about 15 light years in diameter. The open star cluster NGC 6618 lies in the nebula itself and makes the gases of M17 glow. The slightly less bright, detached part of the nebula next to the core is on closer inspection part of the other half of the nebula. But it looks like two nebulae, because a large dark nebula divides the luminous gas.

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.
