Orione, il più imponente e il più bello degli uomini della mitologia Greca e Romana, il gigante cacciatore e figlio di Poseidone, nasconde eccezionali meraviglie. Proprio sotto la sua cintura (non pensate a male) splende l'oggetto celeste più brillante e facilmente osservabile del cielo: la "grande Nebulosa di Orione". Così grande da coprire uno spazio di 24 a.l. e da essere facilmente osservabile ad occhio nudo.

Li, a 1270 a.l. dalla terra, tra gas ionizzati e nebulose a rilessione, ad una temperatura di 10000K nascono stelle e sistemi planetari. Gli studiosi hanno già individuato 700 stelle in fase di sviluppo e più di 150 dischi protoplanetari dal quale si formeranno nuovi sistemi "solari".

Una stella nasce quando una nube di idrogeno ed altri gas si contraggono a causa della propria forza di gravità. La temepratura aumenta rapidamente a causa del collasso e della conversione di energia gravitazionale in energia termica. Se la temperatura sarà sufficiente si innesca la fusione nucleare che da origine ad una protostella.

Può capitare che non tutto il materiale venga catturato dalla forza di gravità prima dell'innesco della fusione nucleare. E' così che intorno alla protostella si forma un disco protoplanetario che accompagna la formazione della stella raccogliendosi in ammassi di materiale che a poco alla voltà prenderano la forma di un pianeta.

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.
