NGC4395 -Galassia - Costellazione dei Cani da Caccia

Revision title: Crop

NGC 4395 è una galassia a spirale di debole brillanza superficiale nella costellazione dei Cani da Caccia. Si trova a circa 14 milioni di anni luce (o 4,3 Mpc) dalla Terra.

La galassia è molto insolita per una galassia di Seyfert, perché non ha un rigonfiamento e viene considerata una galassia nana. ² Il suo nucleo è attivo e contiene uno dei buchi neri super massicci più piccoli con una massa ben misurata. La massa del buco nero centrale è di "solo" 300.000 M☉. Tuttavia, un recente studio ha trovato una massa del buco nero di soli 10.000 M☉.

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.
