Markarian's Chain in the Virgo Cluster

En bit öster om stjärnbilden Lejonet och norr om Jungfrun ligger Virgohopen, som är en galaxhop bestående av upp emot 2000 galaxer. Avståndet från oss är ungefär 55 miljoner ljusår.

Mitt foto visar den del av hopen som kallas Markarian's Chain. Det omfattar 2° x 1.4° eller ungefär 3½ x 2½ fullmånar och i bilden kan man räkna till cirka 35 galaxer.

Det starkt lysande objektet nere i vänster hörn är M87, en av de tyngsta kända galaxerna i universum. Diametern är 120.000 ljusår, vilket är ungefär som Vintergatan, men medan vår egen galax är en platt spiral är M87 mer som en hoptryckt boll och uppskattas innehålla en biljon stjärnor mot Vintergatans futtiga 300 miljarder.
Men, bara en bråkdel av galaxens massa består av stjärnor, vilket endast ger dubbla Vintergatans massa. M87's totala massa beräknas däremot vara 200 ggr vår egen galax.

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.
