Tarantula nebula

La Nebulosa tarantola fu ritenuta in un primo tempo una stella, poi chiamata 30 Doradus;

nel 1751, Nicolas Louis de Lacaille riconobbe la sua natura nebulare.

La Nebulosa Tarantola ha una magnitudine apparente pari ad 8; considerando la sua distanza

di 160.000 anni luce, si tratta di un oggetto estremamente luminoso. Infatti, si tratta della

regione di formazione stellare più attiva del Gruppo Locale di galassie; al suo centro,

un ammasso estremamente compatto di stelle calde e giovani produce la maggior parte dell'energia

che rende visibile la nebulosa.

La reale dimensione della Nebulosa Tarantola è di circa

1.000 anni luce; se fosse posta alla stessa distanza della Nebulosa di Orione

(un'altra regione di formazione stellare, visibile ad occhio nudo) sarebbe 60 volte più grande

della luna piena.

Nelle aree centrali della nebulosa si trova un ricchissimo e compatto

ammasso di stelle, noto come R136a, il quale è il principale responsabile dell'illuminazione

e dell'eccitamento dei gas della nebulosa. Un altro ammasso è Hodge 301.

La Nebulosa Tarantola è stata la sede di un'esplosione di supernova,

la cui luce è giunta a noi nel 1987: la supernova SN 1987a, una delle più studiate,

data la sua relativa vicinanza (fu visibile anche ad occhio nudo, con una magnitudine apparente pari a 4,0)

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.
