M31 - Andromeda Galaxy

----------------------

This image is the result of processing 8 hours of image data I collected last August, of our closest galactic neighbour: the "Andromeda Galaxy".

Although the Andromeda Galaxy has roughly the same amount of total mass as our own Milky Way galaxy, it has more than twice the number of stars (around a trillion stars).

It is located at approximately 2.5 million light years away, which means that the light captured in this image was emitted 2.5 million years ago, when the Earth was undergoing huge ice ages, Mammoths and Saber-toothed tigers thrived and the genus 'Homo' had just started using stone tools.

The latest measurements of European Space Agency's "Gaia" spacecraft suggest that the Andromeda Galaxy will collide with our own Milky Way galaxy in approximately 4.5 billion years.

Also visible in the image are Andromeda's satellite galaxies, M32/NGC 221 (left) and M110/NGC 205 (right).

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.
