Sh2-71

This object is a planetary nebula located over 3,000 light-years away in the constellation of Aquila. It has an unusual, complex and non-symmetric shape. This type of geometry is typically a multi-polar structure due to multiple stars with several pairs of bipolar lobes at different orientations that expelled gas at different times. Although the bright star at the center of the nebula would seem to be the central star, scientists are still debating how this nebula formed and which stars are responsible.

This is a bi-color image using hydrogen and oxygen, with hydrogen being the dominant gas as shown by the reddish color. RGB subs were used to provide realistic star color.

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.
