NGC 4441

This galaxy is located 60 million light years away in the constellation of Draco at a declination of +65 degrees. It spans 4 arc-minutes in our apparent view, which corresponds to an actual diameter of 70,000 light years. This galaxy is classified as a spiral galaxy but it also looks like an elliptical galaxy. A paper (“The H(I) content of the advanced merger NGC 4441”, by Manthey, Aalto, H¨uttemeister and Oosterloo) documents that this galaxy was formed from a merger between a spiral and an elliptical.

The inner disk region looks like a spiral galaxy, with a bright core and numerous faint dust bands. I like the bluish shading around the core as seen in the full resolution view. The outer region is strange and fascinating – numerous looping star streams protruding in various directions. I am surprised that Dr. Arp didn’t pick this one for his catalog – it is more interesting and bizarre than many of his other “peculiar” Arp objects.

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.
