NGC 6537

This planetary nebula, nicknamed the Red Spider Nebula, is located in the constellation of Sagittarius at a declination of -20 degrees. It is a magnitude 12 PN which spans 3 arc-minutes in our apparent view. This is one of the few PN for which we do not know the distance with any degree of confidence.

The nebula has a beautiful bi-polar two-lobed shape, likely due to a binary progenitor star. I find it fascinating that the gas structures appears rippled. I have not seen such complexity in a PN before. Little OIII is present.

The progenitor central white dwarf is shrouded in dust and is believed to be amongst the hottest white dwarfs in existence.

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.
