Comet C/2022 E3 (ZTF), also known as the Green Comet or Circumpolar Comet (because it rotates around the north pole through the day and never sets below the horizon). It is approaching the Earth and will be closest to us around Feb. 1st before it returns to the distant depths of the Solar System. It's showing some very interesting structures, even from a fairly bright suburban sky. Lots of interesting structures: nucleus (an icy/rocky body too small to see anything other than a point), coma (the fuzzy stuff around the nucleus), both a dust and ion (gas) tail, and even an antitail in the opposite direction to the other tails. The comet was also passing in front of a very distant galaxy known as NGC 5894, 130 million light-years away.

This is a composite of 113 frames, 60 sec. each (almost 2 hours total) from suburban Bloomington, Ind. It was processed twice: registered on the comet and separately on the stars and combined in Photoshop. (The comet moves across the sky fast enough that there is noticeable motion in a few minutes. Either the comet or the stars would be trailed in a standard composite).

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.
