Sh2-308 , también designada como Sharpless 308 , RCW 11 o LBN 1052 , [1] y comúnmente conocida como Nebulosa Cabeza de Delfín , es una región H II ubicada cerca del centro de la constelación de Can Mayor , compuesta de hidrógeno ionizado . Está a unos 8 grados al sur de Sirio , la estrella más brillante del cielo nocturno. La nebulosa tiene forma de burbuja y rodea a una estrella Wolf-Rayet llamada EZ Canis Majoris . Esta estrella se encuentra en la breve fase previa a la supernova de su evolución estelar . La nebulosa está a unos 4.530 años luz (1.389 pársecs ) de la Tierra , pero algunas fuentes indican que tanto la estrella como la nebulosa están hasta 5.870 ly (1.800 pc) de distancia. [4] [5] Otros indican que la nebulosa está tan cerca como 1.875 ly (575 pc) de la Tierra.

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.
