The Western Veil Nebula (NGC6960) or Witches Broom Nebula (Vince Castello)

The Western Veil Nebula (NGC6960) or Witches Broom Nebula

This is the Western Veil Nebula (or the Witches Broom Nebula or NGC 6960) is a supernova remnant consisting of oxygen, sulfur, and hydrogen gas. This area of the constellation Cygnus is densely populated with stars and includes regions of heated gas that make up the Cygnus Loop. The entire nebula covers an area of over 3 degrees (3 full moon widths), but this is just one portion of the remnants of the supernova explosion of a star 20 times the size of the sun, that occurred between 10 and 20,000 years ago. Distance from earth about 2400 light years. This filament is around 130 light years across.

This image was taken with a dual band filter exposing mainly light from Hydrogen Alpha (Ha) and Oxygen III (OIII) ionized gases, illuminated by the radiation from area stars.

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.
