Cygnus Loop

The Cygnus Loop is a large, relatively faint supernova remnant located in the constellation of Cygnus.
It is located approximately 1,440 light years from Earth.
It consists of several nebulae. The most famous of these are NGC 6960 (The Witch's Broom or God's Finger), NGC 6992 The Veil Nebula, and Pickering's Triangle (Fleming).

The supernova explosion that triggered the formation of the Cygnus Loop happened about 10,000 years ago. It covers an area of about 80 light years, or 3 degrees of the sky in the constellation of Cygnus. The shock wave from the explosion produced delicate structures of incandescent gas, the visible part of the Loop known as the Veil Nebula, colliding with the stationary gases of the interstellar medium at nearly 20,000 km/s. The result of this is the excitation of the gas molecules. As the gases release their newly acquired energy in radiation of other wavelengths, the nebula's vivid colors are produced, also observed in visible light.

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.
