Lobster claw nebula - Sh 157 (Kabir Jami)

Lobster claw nebula - Sh 157

Sharpless 157, sometimes referred as the Lobster Claw Nebula, is an emission nebula in the constellation Cassiopeia, at approximately 11,050 light years. The predominantly red part of the nebula is a very large hydrogen (H II) region that is ring-shaped by the stellar wind of several giant stars, including the bright and very young Wolf-Rayed star WR 57. The small bright region at the left of centre of the image is Lyn's Bright Nebula 537 (LBN537 or Sharpless 157a). The slightly pink coloured left claw of the lobster mainly consists of highly ionized oxygen (OIII) and other gases. The small open star cluster NGC 7510 is located at the far right of the image.

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.
