Arp 95

This Astrobin Debut Object is a trio of galaxies located in the constellation of Bootes at a declination of +26 degrees. In his Arp catalog, Dr. Arp classified this object into the category of Spiral Galaxies with Elliptical Galaxy Companions on Arms.

The central large spiral is IC 4461. This galaxy, 430 million light years away, spans 30 arc-seconds and is 80,000 light years in diameter. The bright blue stellar-like object in the upper right galaxy disk looks like a foreground star to me.

The elliptical to the left, IC 4463, is also at the same distance as IC 4461. However, I don’t see any signs of interaction between these two galaxies and I don’t agree with Dr. Arp’s “companion” assessment.

The third galaxy, the spiral MCG +05-34-076 to the lower right, is much further away at 860 million light years. It is 100,000 light years in diameter. It has an interesting polar ring type of structure.

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.
