NGC 864

NGC 864 is a barred spiral galaxy in the direction of Cetus. It is estimated to be around 69 million light years away. As a morphological feature, bars in the centers of galaxies indicate a dynamic movement of gas (and stars). While NGC 864 possesses a weak bar- the effects of the structure can be readily seen in the galaxy. The elongated and extremely bright nucleus delineate the bar. When displayed in a non-linear fashion the delicate dust lanes that run along the bar can be discerned. Galactic bars generally stir the interiors of galaxies with flows of gas into and out of the region. Due to their asymmetric concentration of mass, bars can also generate waves of star formation in the outer disk by the oscillatory compression of gas. In the case of NGC 864, the two major arms spring from the ends of the bar. These arms indicate a continual emergence of new star-formation that continues "downstream." A few other barred spirals include: NGC 7479, NGC 255, NGC 266, NGC 1300, M58, NGC 5964, NGC 5921, and many others.

This was a tough one for me. I had to toss a lot of subs. Even though the data was limited I think it came out ok.

Thanks for looking.

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.
