What's in a name? That which we call a nebula by any other name would look as interesting.

Forgive the mooching of Shakespeare. Let's put the quote to the test:

"Little Dumbbell," "Barbell," "Cork," "Butterfly," take your pick.

This little popper has been called all of these by one astronomer or another. To those I'd add "Apple Core" (I'm not the first to suggest).

Today, catalogs call it Messier 76, and NGC 650/651.

In fact, Corker is far beyond our solar system in another spiral arm of the Milky Way, about 2500 light years away. It is an explosion, and we're seeing it not long after the initial event, as it's only about 1 light year across.

First seen in the 1780s, astronomers couldn't decide if it was inside our solar system or a product of a more distant star. Nowadays, modern scientists agree with the latter—that measurements suggest an explosion of a binary star (two stars orbiting each other). How rare is that?!

The image seems to show the initial shedding out from the poles of hydrogen (red), followed by Oxygen, perhaps Nitrogen, and lots of lighter smoke and ash (blue).Then there's those two clumps of something orbiting what would now be dense, tiny neutron stars.

All composed in kind of symmetrical pattern that suggests so many names.

Appropriately, or not, tonight's image processing is accompanied by the Oscar Peterson Trio's version of 𝘘𝘶𝘪𝘦𝘵 𝘕𝘪𝘨𝘩𝘵𝘴 𝘖𝘧 𝘘𝘶𝘪𝘦𝘵 𝘚𝘵𝘢𝘳𝘴.

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.
