Spagetti Nebula (Sh-240)

Sh2-240, also known as Simeis 147 or the Spaghetti Nebula, is a supernova remnant (SNR) located on the border between the constellations Taurus and Auriga. It is about 3,000 light-years away and spans approximately 150 light-years in diameter, making it one of the largest and most diffuse supernova remnants visible from Earth.

Believed to be the result of a supernova explosion around 40,000 years ago, Sh2-240 consists of intricate filaments of ionized gas and faint, tangled structures. It is still interacting with the surrounding interstellar medium, emitting faint optical, radio, and X-ray radiation. At its core, the remnant likely contains a neutron star or pulsar, the collapsed core of the original massive star that exploded.

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.
