Hickson44

Gruppo di galassie nella costellazione del Leone denominato Hickson44 o Arp316 , esso si trova a circa 100 milioni di anni luce di distanza dalla zona in cui e' situata la nostra Via Lattea . Le due galassie a spirale al centro dell'immagine sono NGC 3190 con le sue caratteristiche corsie di polvere deformata e NGC 3187 a forma di S, accanto a loro c'e' la brillante ellittica NGC 3193, mentre più' a destra abbiamo la galassia. a spirale NGC 3185. Come altre galassie dei gruppi di Hickson, questi mostrano segni di distorsione e formazione stellare, come fosse un tiro alla fune gravitazionale che alla fine si tradurrà in fusioni di galassie su una scala temporale cosmica. Il processo di fusione è ora inteso come una parte normale dell'evoluzione delle galassie, inclusa la nostra Via Lattea che si fondera' con la nostra "vicina" Andromeda (M31) distante circa 2 milioni di anni luce. Ho ripreso questo bellissimo gruppo di galassie il 13 e 14 Aprile con luna tramontata e il 27 e 28 prima che sorgesse , piccola curiosita' il fatto che ho dovuto catturare piu' segnale RGB che Luminanza , di solito e' il contrario.

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.
