Sh2-232

Sh2-235 e il sistema di nebulose che si individuano nella parte centrale della costellazione dell'Auriga,

sul bordo di una regione ricca di stelle di fondo a causa della presenza della scia della Via Lattea; la loro posizione

si riesce a trovare facilmente circa 4° a WSW della brillante stella ? Aurigae, che ha una magnitudine apparente pari a 2,65.

Sh2-235 è la nebulosa più brillante del complesso di cui fa parte ed è visibile con un potente telescopio amatoriale o

meglio ancora nelle fotografie a lunga esposizione come una macchia chiara molto pallida; le nubi circostanti sono invece

visibili specialmente in immagini sensibili al vicino infrarosso.

La sua posizione fisica è all'interno del Braccio di Perseo e mostra sia segni di formazione stellare avvenuti in passato,

sia oggetti associati a fenomeni ancora in atto; la regione Sh2-235 è la più attiva del complesso e presenta al suo

interno diversi oggetti stellari nelle prime fasi della loro vita, più un gran numero di sorgenti infrarosse e radio.

La distanza media è stata stimata essere di circa 5870 anni luce.

L'ambiente in cui si trova Sh2-235 è ricco di addensamenti nebulosi in cui si trovano stelle giovani e calde;

fra queste, le più estese, anche se non le più luminose e compatte, sono Sh2-231 e Sh2-232, talvolta indicate con

l'unica sigla LBN 808. Si tratta di due regioni molto evolute la cui stella ionizzante è situata a metà strada fra

le due, ad est del semiarco formato da Sh2-231 e a sudovest del grande complesso di Sh2-232; questa stella è catalogata

come ALS 8476, una nana blu di magnitudine 10,79.

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.
