Arp 138 (Gary Imm)

Arp 138

This object, also known as NGC 4015, is a pair of galaxies located 210 million light years away in the constellation of Coma Berenices at a declination of +25 degrees. This object was classified by Dr. Arp into the odd category of Material Emanating from Elliptical Galaxies.

The bright elliptical is MCG+04-28-109. It is magnitude 14 and is about 70,000 light years in diameter. The smaller magnitude 16 edge-on spiral, obviously closer to us, is MCG+04-28-110.

I don’t believe that these 2 galaxies are close enough to be interacting. I don’t see much disturbance in the edge-on spiral, which would be expected especially given that the other galaxy is an elliptical.

Numerous other galaxies are seen in the background. I particularly like NGC 4005, at upper right.

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.
