NGC 2736 - Pencil Nebula aka. Herschel's Ray

NGC 2736 is part of the Vela Supernova Remnant, located in the constellation Vela. It is also called The Pencil Nebula, or alternately Herschel's Ray, after its discoverer.

John Herschel discovered this object at the Cape of Good Hope on 1 March 1835, and described it as "an extraordinary long narrow ray of excessively feeble light". With dimensions of 30' x 7', the nebula's linear appearance triggered its popular name. A relatively bright star, mentioned by Herschel, is immersed in NGC 2736.

NGC 2736 resides about 800 light-years away, and is the brightest patch of the Vela supernova remnant (also known as the Gum Nebula, not shown). Its thin, braided filaments are actually long ripples in a sheet of glowing gas seen almost edge on. The Vela remnant, now around 100 light-years in diameter, is the expanding debris cloud of a star that exploded about 11,000 years ago. Its shock wave, though having slowed considerably, plows through space at over 500,000 kilometers per hour, sweeping up surrounding interstellar gas.

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.
