NGC 1333

NGC 1333 è una nebulosa a riflessione illuminata da una stella di magnitudine 10,5; la parte meridionale dell'oggetto è invece oscurata in più punti:

una prima banda di nebulosità oscura divide nettamente la scia chiara della nebulosa, la cui parte meridionale viene poi attraversata più volte da altri complessi

nebulosi fino a confondersi con lo sfondo buio. Fra le tante nebulose oscure associate si trovano B1 e B2 a nord-est e B202, B203, B204, B206 e soprattutto B205 a sud-ovest.

Gran parte delle stelle presenti nell'area sono giovani, nella sequenza principale, e sono divisibili in due sottogruppi: il primo, più settentrionale, è quello più vecchio,

mentre più a sud si trova un secondo gruppo più strettamente legato ai gas del complesso nebuloso. Nella parte meridionale sono stati osservati pure diversi getti di materia

provenienti dalle stelle più giovani o ancora in formazione, che contribuiscono a disperdere il gas della regione, probabilmente causando un rallentamento del fenomeno della formazione stellare.

La massa totale della nebulosa e delle stelle ad essa associate si aggira sulle 450 masse solari.

La distanza di questi complessi nebulosi è stimata sui 1000 anni luce.

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.
