Sharpless 176

Sharpless 176 (Sh2-176) is a faint planetary nebula with a hydrogen-rich central star. It was discovered to be a planetary nebula by F. Sabbadin et al in 1977 (Astronomy & Astrophysics, "Sharpless 176: A Large, Nearby Planetary Nebula", March 1977). It is approximately 490 light-years away with estimates for its age ranging from 24,000 to over 180,000 years old based on the computed kinematics (expansion rate and nebular diameter). Expanding at 19 km/sec, Sh2-176 has been estimated to span 3.1 to over 22 light-years across depending on the source. Its asymmetricity is believed to be the result of bow shocks involving the interstellar medium and the nebula itself where the brighter portion of the nebula represents the interaction of the nebula with the interstellar medium as it travels through space. The central star associated with Sh2-176 is a blue subdwarf with a magnitude of 18.74. (ImagingDeepSpace.com)

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.
