Abell 53 #1

This is a little planetary nebula in the constellation Aquila, which is a hard-to-spot constellation right along the Milky Way above the more-familiar Sagittarius. Located about 6,300 lightyears away, this magnitude 14 nebula is about 1 lightyear across. This sounds dim, but because of its small apparent size on the sky (30 arcseconds -- smaller than the width of a sewing needle held at arm's length!), it pops out relatively easily from the background on a camera -- I imagine that with a nebula-boost filter, it could be spotted in something like a 10" or bigger Dob under decent sky conditions.

Anyway, planetary nebulae are the remnants of dying main-sequence stars -- stars roughly the size of our own that can no longer hold onto their outer layers of gas, which are being puffed out into space. Our own Sun will eventually become a planetary nebula (in about 5 billion years, give or take), and might be a lovely little sight for someone else on some other distant planet.

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.
