La Nebulosa del cono (también conocida como NGC 2264) es una región H II en la constelación de Monoceros. Fue descubierta por William Herschel en 1785. La nebulosa se encuentra a 800 pársecs o 2.600 años luz de la tierra. La nebulosa es parte de una nebulosa alrededor del Christmas Tree Cluster, o Grupo Árbol Navideño. El nombre NGC 2264 en el Nuevo Catálogo General se refiere a ambos objectos y no solo a la nebulosa.La difusa nebulosa del cono se llama así por su forma cónica. Se encuentra en la parte sur de NGC 2264, en la parte norte del Christmas Tree Cluster. En la parte norte de Monoceros, justo al norte del punto medio de la línea de Procyon a Betelgeuse.La forma cónica proviene de una nebulosa de absorción oscura que consiste de hidrógeno frío molecular y polvo frente a una débil nebulosa de emisión que contiene hidrógeno ionizado por S Monocerotos, la estrella más brillante de NGC 2264. La débil nebulosa mide aproximadamente siete años luz (con longitud aparente de 10 minutos de arco), y esta a 2700 años luz de la Tierra. Se puede observar también la flecha NGC2261

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.
