California Nebula: NGC 1499

The California Nebula (NGC 1499) was discovered in 1884 by Barnard, a famous American astronomer. So named because it resembles to some the shoreline of the West Coast of the United States, this neubla is about 1200 light years from Earth. All this red hydrogen gas is excited by a single star Xi Persei which is a blue giant star with a mass 30 times that of our sun....but with a luminosity almost 13000 times brighter than our Sun and if you include ultraviolet light it is then 263,000 times more luminous than the sun!

Barnard lived in Tennessee and actually started as a photographer with an astronomy interest! A wealthy philanthropist at the time from NY was offering 200 dollars for the discovery of each new comet. Barnard discovered 5 in short order and used the money to buy himself and his wife a house., launching his astronomy career. He went on to discover 15 comets in total throughout his life as well as many other more famous astronomical discoveries. He received a fellowship to Vanderbilt in Tennessee but never graduated. He did later receive an honorary degree and to this day, his honorary degree from Vanderbilt is the only one they have ever awarded......

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.
