Messier 106

Messier 106 oder NGC 4258 ist eine Balken-Spiralgalaxie vom Hubble-Typ SBbc im Sternbild Canes Venatici. Sie ist schätzungsweise 23 Millionen Lichtjahre von der Milchstraße entfernt und hat einen Durchmesser von etwa 125.000 Lichtjahren.
Der Kern der Galaxie ist aktiv und als Radioquelle seit den 1950er Jahren bekannt. 1995 beschrieben Brent Tully et al., dass das Zentrum einen Jet ausstößt, der in Zusammenhang mit dem im selben Jahr entdeckten massiven zentralen Objekt dieser Galaxie stehen sollte. Dieses Zentralobjekt ist vermutlich ein Schwarzes Loch von knapp 40 Millionen Sonnenmassen.
Die beiden Spiralarme sind durch große Mengen an jungen, massereichen Sternen gekennzeichnet, die in einem bläulichen Licht leuchten. Die Galaxie durchläuft derzeit einen sogenannten »Starburst«, bei dem die Sternentstehungsrate stark erhöht ist.
Das Objekt wurde im Juli 1781 von Pierre Méchain entdeckt.

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.
