The Andromeda galaxy, also catalogued as M31, is maybe the furthest object that can be seen naked eye, with the exception of M33 under pristine skies and exceptional eyes. This spiral galaxy lays around 2,5 million light years away from us.

Because of its size and distance from our Milky Way, Andromeda is approaching us at a speed of 110 km/second (being a blue shifted object!). In a "near future" both will collide creating a new supergalaxy, the Milkomeda.

In the following image, taken from my home observatory in Prades (Catalonia, Spain), you can see M31 and it's two galaxy satellites, M32 (the closer to M31) and M110.

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.
