Andromeda Galaxy & M31

Very proud of this one. Actually, I guess proud isn't the word, more like surprised. First time stacking M31, and figured I'd frame it with the corresponding constellation. So here is a portion of the Andromeda constellation, along with the Andromeda Galaxy off in the distance.

The Andromeda Galaxy (M31 or NGC 224) is a spiral-type galaxy located about 2.5 million light years from Earth. It is the nearest spiral galaxy to the Milky Way, however not the nearest galaxy overall. In 2006, calculations were made using the Spitzer Space Telescope to determine that there were at least twice the number of stars in the Andromeda galaxy (1 trillion) compared to our own (200-400 billion). Our galaxy is expected to collide with M31 in about 3.75 billion years. THAT would be quite a show!!!

Being that the Andromeda Galaxy is about 2.5 million light years from Earth, ponder this... Imagine there were lifeforms on a planet travelling around one of the stars in M31 that were capable of viewing Earth. They would be witnessing life on Earth during the Lower Paleolithic era. The first hominids on this planet were just learning how to use stone crafted tools. Crazy perspective there, huh?

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.
