The Veil Nebula

The Veil nebula is a supernova remnant in the constellation Cygnus about 1500 ly away. This composite shows the Hydrogen alpha (Ha) and doubly ionized oxygen (OIII) emission and contains NGC6992 and NGC6995 collectively known as the Network nebula on the left, and the Witch's Broom, NGC6960, which is close to the bright foreground star 52 Cygni on the right.

The progenitor supernova exploded an estimated 5000-8000 years ago and the full diameter is 3 degrees, giving a size of around 50 ly. The remnant emits radio, infrared, visible light and is also a very bright source of X-rays. As with the Western Veil nebula, the emission filaments are thought to be the edge-on view of the thin shell of expanding gas. The entire 3 degree field contains this gas, but it's only in this edge-on view that the shell is visible. The supernova must've been quite a site to our ancestors. For reference, it's about 4.3x closer than the supernova that left the Crab nebula remnant, M1, in 1054 AD, which had an apparent magnitude of -6.5 at it's peak. For supernovae with the same intrinsic brightness, this would give a 18x increase in brightness, or around 3.2 magnitudes.

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.
