Le Pleiadi (conosciute anche come le Sette sorelle, la Chioccetta o con la sigla M45 del catalogo di Charles Messier) sono un ammasso aperto visibile nella costellazione del Toro. Questo ammasso, piuttosto vicino (440 anni luce),conta diverse stelle visibili a occhio nudo; anche se dagli ambienti cittadini solo quattro o cinque delle stelle più brillanti sono visibili, da un luogo più buio se ne possono contare già dodici. Tutte le sue componenti sono circondate da leggere nebulose a riflessione, osservabili specialmente in fotografie a lunga esposizione prese con telescopi di dimensioni ragguardevoliNotevole è che le stelle delle Pleiadi sono realmente vicine tra loro, hanno un'origine comune e sono legate da forza di gravità. Data la loro distanza, le stelle visibili tra le Pleiadi sono molto più calde del normale, e ciò si riflette nel loro colore: sono delle giganti blu o bianche; l'ammasso conta in realtà centinaia di altre stelle, la gran parte delle quali sono troppo lontane e fredde per essere visibili a occhio nudo. Le Pleiadi sono in effetti un ammasso giovane, con un'età stimata di circa 100 milioni di anni,

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.
