NGC 6500 & NGC 6501

Back to the obscure for today's object! This unassuming pair of galaxies is located in the constellation of Hercules at a declination of +18 degrees.

NGC 6500, on the right, is a 12.5 magnitude spiral galaxy located 140 million light years away. It spans 1.5 arc-minutes in our apparent view, which corresponds to an actual diameter of 70,000 light years. The faint outer edge of the galaxy below the core extends asymmetrically outward. The galaxy disk has interesting subtle color and structure variations.

NGC 6501, on the left, is an elliptical galaxy located slightly further away, at 150 million light years. This galaxy is slightly larger, at 80,000 light years in diameter.

Aside from the star stream extension of NGC 6500 mentioned above, I don’t see any signs of disturbance. I don’t believe that these galaxies are currently interacting, which would be consistent with their distance estimates.

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.
