SIMEIS 147

Simeis 147 ,nota anche come Sh2-240 o Nebulosa Spaghetti=10.5px , è un celebre resto di supernova visibile nella costellazione del Toro, al confine con l'Auriga.La nebulosa si presenta sotto forma di delicatissimi filamenti, più densi nel lato sud-orientale e molto più rarefatta in quello occidentale; sono stati creati da un'antica supernova esplosa a circa 1470 parsec (4800 anni luce) dal Sole, sul Braccio di Perseo. Se le misure di distanza sono corrette, l'oggetto avrebbe una dimensione reale di ben 160 anni luce. La supernova sarebbe esplosa circa 40.000 anni fa, lasciando verso l'angolo meridionale dell'oggetto una pulsar; la stella che ha originato quest'oggetto probabilmente era una membro dell'associazione Auriga OB1 ed era quindi legata all'ammasso aperto M36, dal quale sarebbe sfuggito prima di terminare il suo ciclo vitale.[1]

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.
