NGC-147 and 185 two dwarf spheroidal galaxies that are satellite galaxies of Andromeda (M31)

NGC-147 and NGC-185 are dwarf spheroidal galaxies about 2.58 and 2.08 million light-years
away in the constellation Cassiopeia.  NGC 147 and 185 are members of the Local group of
galaxies and are satellite galaxies of the Andromeda Galaxy (M31).   Unlike most dwarf elliptical
galaxies, NGC 185 contains young stellar clusters, and star formation in recent past. NGC 185
has an active galactic nucleus and is usually classified as a type 2 Seyfert galaxy.
They are separated by approximately 35,000 light-years.

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.
