M31 - Andromeda

Link: https://www.palaferri.com/m31-galassia-andromeda/

M31, also known as the Andromeda Galaxy, is a spiral galaxy located about 2.5 million light-years away from Earth in the constellation of Andromeda. It is the closest galaxy to our Milky Way and one of the brightest and most observable galaxies in the night sky.M31 is quite large, with an estimated diameter of about 220,000 light-years, roughly twice the size of our galaxy. It contains hundreds of billions of stars, solar systems, and interstellar gas and dust clouds.The Andromeda Galaxy is a spectacular sight to observe through a telescope or even with the naked eye under dark sky conditions. It appears as a bright elongated patch in the sky, with a luminous core surrounded by spiral arms, similar to those of our Milky Way.M31 is part of the Local Group, a group of galaxies that also includes the Milky Way, the Triangulum Galaxy (M33), and several other smaller galaxies. It is the largest and most massive galaxy in the Local Group.Due to its proximity and size, the Andromeda Galaxy is one of the most studied and photographed objects by astronomers. It is a significant research target for understanding galaxy formation and evolution, as well as cosmology of the Universe.Interestingly, due to its approach toward the Milky Way, M31 and our galaxy are moving toward each other at a speed of about 110 kilometers per second. In a few billion years, it is predicted that the two galaxies will merge to form a larger elliptical galaxy.

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.
