CTB1 The Garlic Nebula in HOO With RGB Stars

The Garlic Nebula (CTB 1 / Abell 85 or LBN 576) is a supernova remnant in the constellation cassiopea. It is 9780 light years away, spans 98 light years in diameter, and is beleived to be about 10,000 years old. It was originally incorrectly labeled as a planetary nebula by George Abell giving it the designation Abell 85.

In 1960 Robert W. Wilson (who later won the Nobel Prize with Arno Penzias for discovering the cosmic background radiation) and J. G. Bolton properly cataloged it as part of an early radio telescope survey. This list was known as CalTech observatory list B, hence the CTB designation. [1]

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.
