Sh2-119 - The Clamshell Nebula

The Sh2-119 Nebula, commonly referred to as the Shell Nebula, is a captivating nebular formation located in the Cygnus constellation within the Milky Way. To locate it, you simply need to look about 2 degrees west of the stunning North America Nebula or 9 degrees west of the bright star Deneb. Interestingly, it appears to partially envelop the fifth-magnitude star 68 Cygni. This celestial wonder can be observed using a medium-powered amateur telescope and presents an even more spectacular display through long-exposure photographs.The Shell Nebula earns its name due to its distinctive structure resembling two shells arranged to the east and west of the 68 Cygni star. The eastern part is the broader and more visually striking of the two. A captivating detail is the presence of delicate filaments and pockets of dark nebulosity in the southern region of the nebula. These features create a striking contrast with both the brightness of the nebula itself and the rich stellar background.The Shell Nebula is estimated to be located at a distance of around 2200 light-years from Earth. Its light provides us with a snapshot in time of a delicate cosmic process: the result of material expelled from a star in its declining phase. This phenomenon offers valuable insights into the circulation of gas and stellar material in the universe, as well as an opportunity to contemplate the beauty and intricacy of celestial processes at work.Keep in mind that astronomy is a field in constant evolution, and further observations and discoveries may continue to unveil new details and nuances of this fascinating nebula in the future.

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.
