NGC 3504 and NGC 3512

This pair of magnitude 13 spiral galaxies is located in the constellation of Leo Minor at a declination of +28 degrees. Distance measurements are a bit uncertain – both appear to be in the neighborhood of 70 million light years away but, based on their relatively undisturbed structures, I do not think that they are interacting with each other.

NGC 3504, at lower right, spans 2.5 arc-minutes in our apparent view. This corresponds to a diameter of 50,000 light years. I love the galaxy structure – a bright white core connected by a faint yellow bar to an inner ring which has bright blue star cloud ansae. The highlight is the pseudo-ring in the outer disk.

NGC 3512, at upper left, is smaller at a diameter of 30,000 light years. This galaxy has an odd arm structure and an asymmetric disk.

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.
