La Galaxia de Andrómeda, también conocida como Galaxia Espiral M31, Messier 31 o NGC 224, es una galaxia espiral gigante. Es el objeto visible a simple vista más alejado de la Tierra (aunque algunos afirman poder ver a simple vista la Galaxia del Triángulo, que está un poco más lejos). Está a 2,5 millones de años luz (775 kpc)2 en dirección a la constelación de Andrómeda. Es la más grande y brillante de las galaxias del Grupo Local, que consiste en aproximadamente 30 pequeñas galaxias más tres grandes galaxias espirales: Andrómeda, la Vía Láctea y la Galaxia del Triángulo.

La galaxia se está acercando a nosotros a unos 300 kilómetros por segundo,4 y se cree que de aquí a aproximadamente 3.000 a 5.000 millones de años podría colisionar con la nuestra y fusionarse ambas formando una galaxia elíptica gigante.

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.
