NGC 2371 / 2372 Planetary Nebula or PK 189 +19.1

NGC 2371 is a dual lobed planetary nebula at a distance of 4,400 light years in Gemini. It was given 2 NGC numbers perhaps because it can appear as 2 separate halves in an eyepiece.

There are 2 jets of material moving away from the central star that are 180 degrees from each other in the image, created by radiation interacting with the expanding cloud of material around the star. Astronomers believe these jets match the rotational axis of the central star, and that this axis has moved over the last thousand years perhaps due to a companion star. The hubble image of these jets is below:

The central part of the nebula measures 1 light year across, for those who have wondered what a light year looks like from a distance of 4,400 light years.

This object showed the most detail in OIII as expected. The SII channel yielded only the 2 jets above.

The full size image shows these jets clearly (for a C11

).

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.
