Salt, Pepper and Ice - Comet 21P/Giacobini-Zinner flying-by M37 open cluster

21P/Giacobini-Zinner, icy dirtball virtually flying-by the open cluster M37.

Funfact I

September 11 1985, after being reactivated, NASA's spacecraft ICE (International Cometary Explorer) achieved the 1st ever cometary encounter by passing through this comet's plasma tail.

September 11 2018, and after several loops around the sun, this comet passed though its closest approach to earth.

Funfact II

21P/Giacobini-Zinner comet is responsible for the meteor shower Draconids in October 8, but this is the only meteor shower that also named after its comet, the other name is Giacobinis

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.
