NGC 2438 (PK 231+4.2)

NGC 2438 (PK 231+4.2) is a planetary nebula about 3,000 light-years away in the constellation Puppis. It was discovered by William Herschel on March 19, 1786. NGC 2438 appears to lie within the cluster M46, but it is most likely unrelated since it does not share the cluster's radial velocity.

On this image seen another interesting object in the form of a reddish receptacle, located to the left (almost nine hours) of NGC 2438.

The Calabash Nebula (also known as the Rotten Egg Nebula and OH231.8+4.2) is a planetary nebula with a width of about 1.4 light-years and located at a distance of about 5000 light-years from Earth. This nebula is likely to turn into a complete bipolar planetary nebula over the next 1000 years.

This image taken over several nights in March, April 2019.

The color is made by the Bicolor technique.

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.
