Spaghetti Nebula (Sh 2-240, Simeis 147) - 9 Panel Mosaic (Ara Jerahian)

Celestial hemisphere: Northern · Constellation: Taurus (Tau) · Contains: NGC 1996

Spaghetti Nebula (Sh 2-240, Simeis 147) - 9 Panel Mosaic

This is my 9-panel mosaic of the Spaghetti Nebula, also catalogued as Sharpless 2-240, Simeis 147, and SNR G180.0-01.7, is a supernova remnant of extremely low brightness. This image is of the Ha signal in the R channel.

The remnant has an angular width of approximately 3 degrees (6 full moons!!), as is estimated to be at a distance of approximately 3000 light-years, and an age of approximately 40,000 years.

It is believed that after its stellar explosion a rapidly spinning neutron star known as pulsar PSR J0538+2817 was left behind in the nebula core, emitting a strong radio signal.

I hope you enjoy!

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.
