The Spaghetti nebula, Simeis 147

The Spaghetti Nebula, Simeis 147, Sharpless 2-240, is a large, extremely faint supernova remnant located on the border between the constellations of Taurus and Auriga about 3 degrees east of Elnath (or Alnath), Beta Tauri.

Also known as SNR G180.0-01.7, the faint filamentary structure of the nebula spans more than 3 degrees of sky, or 6 full moons across. This spherical shell is 150 light years in diameter with an estimated distance of 3,000 light years.. The supernova explosion, which occurred about 35,000 years ago, formed the nebula, and at its core, is a spinning neutron star known as pulsar PSR J0538+2817, emitting a strong radio signal.

Simeis 147 was discovered by Grigori Abramovich Shajn and V.T. Hase in 1952 at the Crimean Astrophysical Observatory at Simeis in the former U.S.S.R. with a 25-inch Schmidt camera on photographic plates.

A small ionized HII nebula, SH2-242 (LBN 826), is in the lower left of the image.

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.
