The Elephant's Trunk (Gabriele Piantadosi)

The Elephant's Trunk

La Proboscide di Elefante (vdB 142) è un piccolo sbuffo di gas interstellare e polveri scure che risaltano perchè hanno la fortuna di essere di fronte ad una luminosa nebulosa ad emissione (IC1396) nella banda dell'idrogeno ionizzato (HII) simile nella forma e nelle caratteristiche alla più famosa nebulosa Rosetta. Tra le polveri di questo sbuffo l'energia che, da un lato ha ionizato la nebulosa circostante dall'altro ha incrementato la pressione della proboscide, alimenta le fornaci dove sono già nate diverse stelle molto "giovani" (meno di 100.000 anni). Il buchino nella proboscide è stato formato proprio dai venti di una delle primissime stelle nate.

The Elephant Trunks (vdB 142) is a small puff of interstellar gas and dark dust that stands out because it is lucky enough to be in front of a bright emission nebula (IC1396) in the ionized hydrogen (HII) band similar in shape and characteristics to the more famous Rosetta nebula. In the dust of this puff, the energy that has ionized the surrounding nebula on the one hand and increased the pressure of the trunk on the other, feeds the furnaces where several very "young" (less than 100,000 years old) stars have already been born. The tiny hole in the trunk was formed by the very winds of one of the very first stars born.

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.
