NGC 1023

NGC 1023 is a barred lenticular galaxy, approximately 34 million light years away, and belongs to the NGC 891 group of galaxies. It has a visual magnitude of 9.4, with a very bright core surrounded by a rather faint halo, giving it overall dimensions of 7.5x3 arc minutes. Astrophysically, it has a very rapidly rotating nuclear region, suggesting the presence of a massive black hole. Also, a large population of globular clusters has been detected, including some very large ones which appear to be similar to the globulars of M31. Halton Arp included NGC1023 as the 135th entry in his “Catalog of Peculiar Galaxies” as “an elliptical galaxy with nearby fragments”. The only nearby fragment appears to be NGC 1023A, a very faint diffuse irregular system located on the southeast edge of NGC 1023. Arp suggests that PGC 10169, a bit further to the east, may be another fragment. Although both of these galaxies are very near NGC 1023, the appearance of the main galaxy does not show the typical effects of tidal interactions, which are almost certain to have occurred.

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.
