Descripción:

NGC 2359 es una nebulosa de emisión en la constelación de Canis Major situada a algo más de 8 grados de Sirio (a Canis Majoris). Su inusual forma, semejante al casco de un guerrero vikingo, ha llevado a que sea conocida también como Nebulosa del Casco de Thor. Puede ser observada, en cielos oscuros, con telescopios pequeños a 47x con la ayuda de filtros del tipo Oxígeno III.

La estrella que se encuentra en el interior de la burbuja, denominada WR 7 (HD 56925), posee magnitud aparente 11,5. Es una estrella de Wolf-Rayet y es la fuente que ilumina esta nebulosa de Wolf-Rayet. La nebulosidad es el resultado de la interacción entre el viento estelar procedente de la caliente estrella y la materia interestelar. El viento comprime la materia interestelar produciéndose una burbuja de gas en torno a la estrella. La masa de la burbuja se estima en unas 20 masas solares. Aunque de naturaleza similar a la Nebulosa Burbuja (NGC 7635), la interacción con una nube molecular vecina parece haber contribuido a moldear la compleja forma de la nebulosa.

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.
