NGC 7678 (One Heavy Arm) in Pegasus

NGC 7678, with one particularly prominent arm, is located approximately 164 million light-years away in the constellation of Pegasus (the Winged Horse). With a diameter of around 115,000 light-years, this bright spiral galaxy is a similar size to our own galaxy. It was discovered in 1784 by William Herschel.

The galaxy's heavy arm stems from an increased density of stars' gas in the area. Formations of spiral galaxies may be influenced by magnetic fields, and variations in the intensity and flow of those fields could alter the distribution of star-forming gases. The heavier arm was likely a recipient of more gas earlier in the lifespan of the galaxy, allowing more stars to form.

NGC 7678 is among the 338 galaxies presented in the Atlas of Peculiar Galaxies, which organizes peculiar galaxies according to their unusual features. Cataloged there as Arp 28, this galaxy is listed together with six others in the group “spiral galaxies with one heavy arm.”

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.
