Andromeda Galaxien M31, M32 & M110

Die Andromedagalaxie ist 2,5 Millionen Lichtjahre entfernt. Sie hat einen Halo-Durchmesser von circa einer Million Lichtjahren und ist damit das größte Mitglied der Lokalen Gruppe von Galaxien. Die Andromedagalaxie hat eine Gesamtmasse von etwa 200 bis 400 Milliarden Sonnenmassen. Zusammen mit der Milchstraße gehört sie zu den beiden massereichsten Galaxien der Lokalen Gruppe. Die Gesamtmasse kann nur ungenau geschätzt werden, weil der prozentuale Anteil Dunkler Materie mit zunehmender Entfernung vom Zentrum der Andromedagalaxie sprunghaft ansteigt.[3]

Neueste Untersuchungen zeigen, dass die Galaxie von einem riesigen kugelförmigen Halo aus dünn verteilten roten Riesensternen umgeben ist. Noch in einer Entfernung von 500.000 Lichtjahren vom Zentrum der Galaxie wurden Sterne nachgewiesen. Der Durchmesser der sichtbaren Scheibe beträgt etwa 140.000 Lichtjahre. Das Milchstraßensystem hat nur einen Durchmesser von etwa 100.000 Lichtjahren. Der nächstkleinere Begleiter der Lokalen Gruppe, M 33 (oder Dreiecksnebel), hat einen Durchmesser von etwa 50.000 Lichtjahren. Nach neuesten Erkenntnissen enthält M31 etwa eine Billion Sterne, während das Milchstraßensystem 100 bis 200 Milliarden Sterne enthält. Die Andromedagalaxie ist von mehr als zehn kleineren Satellitengalaxien umgeben, von denen zwei elliptische Galaxien als M 32 und M 110 ebenfalls im Messier-Katalog verzeichnet sind.

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.
