NGC 2237 Nebulosa Roseta (2P Mosaic)

La nebulosa Roseta es una región H II grande y circular, ubicada en el borde de una gigantesca nube molecular en la constelación del Unicornio Monoceros, situada en la banda de la Vía Láctea. El cúmulo abierto NGC 2244 (Caldwell 50) está estrechamente asociado con la nebulosa, en virtud de que las estrellas del cúmulo se han formado de la materia de la misma.

Las estrellas de NGC 2244 se formaron a partir del gas circundante hace sólo cuatro millones de años y emiten luz y viento que definen la apariencia de la nebulosa. Luz de alta energía proveniente de las jóvenes estrellas brillantes de NGC 2244 ioniza las nubes de hidrógeno para crear la apariencia de nebulosa de emisión roja. El viento de partículas calientes que fluye desde el cúmulo contribuye a un complejo enjambre de gas y de filamentos de polvo mientras lentamente se van del centro del cúmulo. NGC 2244 mide cerca de 50 años luz de ancho y se ubica a 4500 años luz de distancia, es visible con binoculares hacia la constelación del Unicornio.

Las estrellas más brillantes y masivas del cúmulo son HD 46223, de tipo espectral O4, con una luminosidad 400.000 veces la del Sol y aproximadamente 50 veces más masiva, y HD 46150, de tipo espectral O5, 450.000 veces más luminosa que nuestra estrella, y hasta 60 veces más masiva, aunque esta última puede ser en realidad una estrella binaria.

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.
