M45 PLEYADES (2Panel Mosaic)

Las Pléyades o Las siete hermanas (Messier 45 o M45) es un cúmulo estelar abierto que contiene estrellas calientes de tipo espectral B, de corta edad, ubicadas en la constelación de Tauro. Está entre los cúmulos estelares más cercanos a la Tierra, y es el cúmulo mejor visible a simple vista en el cielo nocturno. Las Pléyades albergan un prominente lugar en la mitología antigua, así como una diversidad de significados en diferentes culturas y tradiciones.

El cúmulo está dominado por estrellas calientes extremadamente azules y luminosas que se han formado en los últimos 120 millones de años. El polvo que forma una débil nebulosidad de reflexión alrededor de las estrellas más brillantes se pensó en un principio que provenía de una disgregación de la propia formación del cúmulo (de ahí el nombre alternativo para nebulosa Maia en vez de estrella Maia), pero ahora se sabe que es una nube de polvo no relacionada en el medio interestelar, a través de la cual las estrellas están pasando actualmente. Y lo anterior se basa en los diferentes valores obtenidos de la velocidad radial de las Pléyades, y de la velocidad radial de la nebulosa que pareciera envolverlas. Simulaciones por ordenador han mostrado que las Pléyades se formaron probablemente a partir de una configuración compacta que se asemeja a la nebulosa de Orión. Los astrónomos estiman que el grupo va a sobrevivir aproximadamente durante otros 250 millones de años, tiempo después del cual se dispersará debido a las interacciones gravitacionales en su entorno galáctico.

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.
