Cygnus Loop, a group of bright nebulae (Lacework Nebula, Veil Nebula, and the nebulae NGC 6960, 6979, 6992, and 6995) in the constellation Cygnus, thought to be remnants of a supernova—i.e., of the explosion of a star probably 10,000 years ago.

The Loop, a strong source of radio waves and X-rays, is still expanding at about 100 km (60 miles) per second. It lies about 1,800 light-years from Earth.

Several components have separate names and identifiers, including the "Western Veil" or "Witch's Broom", the "Eastern Veil", and Pickering's Triangle. Efforts have been made recently to measure the distance using the motions of the nebular gas directly, with published estimates suggesting a firm distance of fewer than 2600 light-years.

The Eastern Veil nebula appears on the left while the Western Veil (Witch’s Broom) nebula is on the right. Pickering’s Triangle is just to the upper left of the Western Veil.

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.
