NGC 3023 and NGC 3018 are a pair of galaxies in Sextans. The system is interesting because of the presence of Markarian (Mrk) 1236 - an intensely bright blue/ultraviolet source appearing within NGC 3023. Although unclear, it is believed to be a very active giant star forming region. The spectrum of Mrk 1236 resembles that of a Wolf-Rayet star, suggesting very recent star formation (within the past few million years before this light was emitted). NGC 3023 and NGC 3018 appear to be interacting and this would explain the vigorous star formation and considerable UV activity as recorded by GALEX. Both galaxies show distorted spiral arms and were probably barred spiral galaxies before their interactions started. They are about 31.2 megaparsecs (or about 102 million light years) from Earth. Despite extensive searches I have been unable to find any deep images of these targets, and thus believe this image to be the first.
Thanks to Owen Brazell for providing the technical details on these galaxies.

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.
