Western Veil Nebula

Western Veil Nebula is a part of the Veil Nebula, which has a diameter of around 100 light years. It is a supernova remnant which was created after a vast and violent explosion of a giant star. Astronomers now believe that the original giant star generated such strong cosmic winds that it blew a hole right through the centre of the interstellar gases before the explosion even took place. When the star finally exploded, the shock waves generated by the explosion impacted this surrounding gaseous shell, which created the glow observers still see today. In fact, the shock wave is continuing to unfold at an estimated 40 km/second (one million miles per hour). Photos taken in 1997 and photos taken in 2015 highlight the ongoing movement within the nebula. By tracking individual knots, or filaments of hydrogen gases, astronomers can in turn track how the Veil Nebula itself is expanding and changing.

Taken over a couple of nights from a location close to central London.

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.
