In the center of the image is the galaxy M 106, also known as NGC 4258. It is about 23 million light-years away and is 13 billion years old. The galaxy contains 400 billion stars. At the top of the image, the two galaxies NGC 4226 and 4217 (constellation Canes Venatici ) can be seen in the northern sky. The distance of NGC 4226 is estimated to be 333 million light-years from the Milky Way, more than 100 times the distance to Andromeda Galaxy M 31. The diameter of NGC 4226 is about 120,000 light-years.Together with NGC 4217 it forms the optical galaxy pair Holm 354.(Source: including Wikipedia)

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.
