Messier 84 Cadena de Markarian

La cadena Markarian es una colección de galaxias del cúmulo de la Virgen. Cuando se ven desde la Tierra, las galaxias se encuentran a lo largo de una línea suavemente curvada. Charles Messier descubrió por primera vez dos de las galaxias, M84 y M86, en 1781. Las otras galaxias vistas a la cadena fueron descubiertas por William Herschel y ahora se conocen principalmente por sus números de catálogo en el New General Catalogue de John Louis Emil Dreyer, publicado en 1888. Finalmente recibió el nombre del astrofísico soviético armenio, Benjamin Markarian, que descubrió su movimiento común observándola intensamente a principios de los años sesenta.

La cadena de Markarian en sentido estricto incluye las galaxias M84 (NGC 4374), M86 (NGC 4406), NGC 4435, NGC 4438, NGC 4461, NGC 4473 y NGC 4477. Algunos autores también añaden otras galaxias como NGC 4458.

Salvo NGC 4406, que se acerca a la Tierra a una velocidad radial de unos 150 km/s, las otras galaxias se alejan de la Tierra a velocidades de 70 a 2.200 km/s.

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.
