La galaxie d'Andromède, également désignée M31 dans le Catalogue de Messier et NGC 224, est une galaxie spirale située à environ 2,55 millions d'années-lumière du Soleil, dans la constellation d'Andromède.
Appelée grande nébuleuse d’Andromède jusqu'à ce que sa vraie nature ait été reconnue dans les années 1920, la galaxie d'Andromède est la galaxie spirale la plus proche de la Voie lactée (toutes classes confondues, la galaxie la plus proche est la naine du Grand Chien) et le plus grand membre du Groupe local d'une soixantaine de galaxies individuelles dont toutes deux font partie. D'un diamètre d'environ 220 000 années-lumière, elle contiendrait environ mille milliards d'étoiles, deux à cinq fois plus que notre galaxie.

Avec une magnitude visuelle de 3,4, la galaxie d'Andromède est l’une des rares galaxies observables à l'œil nu depuis la Terre dans l’hémisphère nord. C’est également l'un des objets les plus étendus de la voûte céleste, avec un diamètre apparent de 3,18°, soit plus de six fois le diamètre apparent de la Lune observée depuis la Terre.

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.
