As a sun-like star begins to deplete it’s hydrogen fuel, a sequence of interesting change is initiated. The core, unable to support its own crushing gravity, compresses and increases dramatically in temperature. In an opposite fashion, the outer atmosphere swells and cools under the intense pressure from within. A red giant is born.

Though there are several possible outcomes, many stars begin to gradually shed the outer atmosphere to deep space. This is the beginning of a planetary nebula.

As the core continues its collapse it emits extreme ultraviolet radiation. The radiation ionizes the gasses of the nebula giving rise to a wonderfully colorful and intricate design.

In this case, the stellar parent is a binary star system. This pair, one dying, sculpts a unique and beautifully complex nebula. Romantic or cannibalistic?

As always, enjoy and let me know what you think in the comments!

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.
