C/2020 F3 (NEOWISE)

La cometa c/2020 F3 Neowise è divenuta in questi giorni un soggetto estremamente interessante nel mondo dell'astronomia amatoriale e non. Infatti, era da tempo che non si vedeva brillare ad occhio nudo una cometa come questa, soprattutto dopo le due interessanti (ma non così tanto) comete che sono passate all'attenzione nella prima parte di quest'anno ma che non sono riuscite a brillare a sufficienza.

Visibile ad occhio nudo, la cometa è stata scoperta il 27 marzo 2020 dal telescopio spaziale Neowise e ha raggiunto il perielio il 3 luglio. C/2020 F3 possiede una bella chioma luminosa (la chioma di una cometa è l'atmosfera che si forma attorno al nucleo di roccia e di gas in sublimazione) e due code molto singolari: la prima, la più luminosa, è formata da componenti in sublimazione mentre la seconda, che risulta meno luminosa, è formata da particelle ionizzate per effetto del vento solare.

La ripresa è stata ottenuta da Emanuele La Barbera e Mario Lauriano presso Monte Pellegrino a Palermo.

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.
