Objekt:

Sh2-101 liegt im Schwan. Er ist ca. 6000 ly von uns entfernt.

Cygnus X-1 ist ein Röntgen-Doppelstern. Die Energie der Abstrahlung entspricht in etwa 10.000 Sonnenleuchtkräften.

Der Hauptstern ist ein Blauer Riese, der 300.000–400.000mal so hell wie die Sonne ist. Er hat etwa den 15-17fachen Durchmesser der Sonne, rund 40±10 Sonnenmassen und trägt die Bezeichnung HD 226868. Die beiden Doppelsternkomponenten von Cyg X-1 umkreisen einander in 5,6 Tagen. Dabei ist der Abstand nur etwa doppelt so groß wie der Radius des Hauptsterns. Es wird vermutet, dass der Blaue Riese durch den kontinuierlichen Sternwind in 400.000 Jahren eine Masse in der Größenordnung der Sonne verliert. Das Alter der Konstellation wird auf 5 Millionen Jahre geschätzt. Die Röntgenstrahlung entsteht dadurch, dass die Masse des Hauptsterns zu dem schwarzen Loch gezogen wird, wo sie eine Akkretionsscheibe bildet, die sich aufgrund der Reibung auf einige Millionen Grad erhitzt und dadurch Röntgenstrahlung abgibt. Spätere Forschungen ergaben eine sehr schnelle Umdrehung von 790/Sekunde. Die Entfernung von Cygnus X-1 konnte zunächst nur schwer genau bestimmt werden, da bei solch großen Distanzen die Parallaxe des Objekts in der Größenordnung des möglichen Messfehlers lag. Je nach Quelle wurden zwischen 6500 und 8200 Lichtjahre angegeben.

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.
