Hickson 44 NGC 3190-93-87-85 ARP316

Arp 316 è nella classe Galaxy Groups. Questo gruppo, incluso NGC 3185, è anche conosciuto come Hickson 44. Gruppo di galassie nella costellazione del Leone (Leo), con NGC 3185 (Sba), NGC 3187 (SBc / P), NGC 3190 ( Sa) e NGC 3193 (E2).

Le quattro galassie prominenti viste in questa immagine appartenenti ad uno dei gruppi, Hickson 44, si trova a circa 100 milioni di anni luce di distanza verso la costellazione del Leone. Diverse misurazioni non basate sul rosso danno una distanza di 24,506 ± 2,994 MPC (~ 79,9 milionia.l.)

Le due galassie a spirale al centro in basso dell'immagine sono NGC 3190 con le sue caratteristiche corsie di polvere deformate e NGC 3187 a forma di S.insieme alla brillante ellittica, NGC 3193 in basso a destra, sono anche note come Arp 316.

La spirale in alto a sinistra è NGC 3185, il quarto membro del gruppo Hickson. Come altre galassie nei 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.

Ci sono molte più galassie nel campo. L'ispezione ingrandita della foto rivelerà anche una moltitudine di piccole galassie, i piccoli punti non sono stelle, ma galassie situate a centinaia di milioni di anni luce di distanza.

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.
