Pencil Nebula / Herschel’s Ray - NGC 2736

NGC 2736's glowing structure was formed from material ejected in a supernova explosion about 11,000 years ago. It is part of the giant Vela SNR (supernova remanent) in the southern constellation Vela (the Sail) and was discovered on March 1, 1835 by John Herschel from the Cape of Good Hope.

The Pencil Nebula is about 815 light-years (250 parsecs) from the Solar System and moving at a speed of about 644,000 kilometers per hour (400,000 mph).

The nebula's glow comes from dense gas regions struck by the supernova shockwave. The different colors in the nebula provide information about the cooling process. Some regions are still so hot that the emission of ionized oxygen atoms dominates (blue in the image).

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.
