NGC7479 is a barred spiral galaxy discovered by William Herschel in 1784, located some 106 Million Light-Years distant towared the Constellation Pegasus. It is a Seyfert type galaxy with a very active and strong bar being fed by the infall of gas along the dusty bar structure. Two major arms seem to form an off-center ring, and these arms along with the outer reaches of the galaxy support very active blue star forming areas, giving the entire galaxy a bluish tint, along with ample gas, dust and HII regions. The galaxy is approximately 100,000 Light-Years in diameter. Studies indicate that the galaxy recently absorbed a merger with a galaxy with arms opening in the opposite direction, showing only in radio continuum.

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.
