The Pencil Nebula (also known as NGC 2736) is a nebula in the southern constellation of Vela (Sails of the Ship), located about 800 light-years from Earth. The emission nebula is part of a larger H II region (a region of ionized hydrogen gas) illuminated by radiation from younger, hotter stars at the nebula's center. It is part of a larger structure called the Vela Supernova Remnant, which is the result of a supernova explosion that occurred around 11,000 to 12,000 years ago.

The Pencil Nebula got its name because of its unusual shape, resembling a pencil or a spear. This effect is caused by the presence of a dark band of dust running through the nebula, giving the impression of a "pierced" celestial body. This band of dust may actually help the hydrogen gas in this area become denser and cooler, favoring the formation of new stars.

It was first observed by the French astronomer Abbé Nicolas Louis de Lacaille in 1751 and later studied by the British astronomer John Herschel in the 19th century.

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.
