The "Eye of God": NGC 7293, Caldwell 63, a.k.a. the "Helix Nebula" or even the "Eye of Sauron", is a beautiful jewel found in the Aquarius constellation. This planetary nebula is one of the closest to Earth and is located 650 light-years away and has 2.87 light-year radius. It is formed by an intermediate to low-mass star, which sheds its outer layers near the end of its evolution. The remanent stellar core will become a white dwarf star, but is glow is so energetic that it causes the previously expelled gases to brightly fluoresce. Note that outer layers resemble a DNA "helix", so one of the names of this object is derived from this fact.

Planetary nebulas are unrelated to planets, but as they have a characteristic rounded shape, the name stuck.

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.
