La nebulosa proboscide dell'elefante è una concentrazione di gas e polveri interstellari nel ammasso stellare IC 1396 -

una regione di gas ionizzato trova nella costellazione di Cefeo circa 2.400 anni luce di distanza dalla Terra.

La parte della nebulosa qui ripresa è un denso globulo IC 1396A, è comunemente chiamato nebulosa proboscide

dell'elefante per il suo aspetto a lunghezze d'onda della luce visibile, dove c'è una macchia scura, con un luminoso,

orlo. Il cerchio luminoso è la superficie della nube densa che viene ionizzato e illuminato da una brillante,

stella di grande massa che è appena a ovest di IC 1396A.

IC 1396 L'intera regione è ionizzata dalla stella massiccia. Nebulosa proboscide dell'elefante, contenente diverse

stelle molto giovani (meno di 100.000 anni).Stelle che sono stete scoperete in riprese all'infrarosso nel 2003.

Due stelle più vecchie (ma ancora giovane, un paio di milioni di anni, secondo gli standard

di stelle, che vivono per miliardi di anni) sono presenti in una piccola cavità circolare nella testa del globulo.

Venti stellari provenienti da queste giovani stelle possono avere svuotato la cavità.

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.
