NGC 4125

This object is an elliptical galaxy located 80 million light years away in the constellation of Draco at a declination of +65 degrees. This 9.7 magnitude galaxy spans 6 arc-minutes in our apparent view, which corresponds to an actual diameter of 130,000 light years.

This is an unusual elliptical galaxy. The April 2020 issue of Astronomy magazine describes it as having a “nearly stellar nucleus”. The January 2020 issue of the same magazine says that this galaxy is “a peculiar massive elliptical galaxy in which evolved stars produced in a merger-triggered burst of star formation are pumping large amounts of gas and dust into the galaxy’s interstellar medium”. Odd ellipticals and past mergers seem to go hand-in-hand.

I find two things particularly unusual. One is the faint dust clouds which are seen in the immediate vicinity around the core. The second is the faint star stream pattern which extends beyond the bright horizontal oval region. I see at least 7 lobes spreading outward, making the galaxy look a bit like a big fuzzy star.

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.
