M1 Nebulosa del Cangrejo

La nebulosa del Cangrejo (M1, NGC 1952, Taurus A y Taurus X-1) es un resto de supernova de tipo plerión. La nebulosa fue observada en 1731 por John Bevis. Es el resto de una supernova que fue observada y documentada, como una estrella visible a la luz del día, por astrónomos chinos y árabes el 4 de julio de 1054 (SN 1054). La explosión se mantuvo visible durante 22 meses. Con este objeto, Charles Messier comenzó su catálogo de objetos no cometarios. Situada a una distancia de aproximadamente 6300 años luz (1930 pc2) de la Tierra, en la constelación de Tauro, la nebulosa tiene un diámetro de seis años luz (1,84 pc) y su velocidad de expansión es de 1500 km/s.

El centro de la nebulosa contiene un púlsar, denominado PSR B0531+21, que gira sobre sí mismo a 30 revoluciones por segundo, emitiendo también pulsos de radiación que van desde los rayos gamma a las ondas de radio. El descubrimiento de la nebulosa produjo la primera evidencia que concluye que las explosiones de supernova producen pulsares.

La nebulosa sirve como una fuente de radiación útil para estudiar cuerpos celestes que la ocultan. En las décadas de 1950 y 1960, la corona solar fue cartografiada gracias a la observación de las ondas de radio producidas por la nebulosa del Cangrejo que pasaban a través del Sol. Más recientemente, el espesor de la atmósfera de Titán, satélite de Saturno, fue medido conforme bloqueaba los rayos X producidos por 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.
