A Ghostly Visit...Comet C/2020 S3 Erasmus closes in on Planetary Nebula Abell 33

On the morning of October 22, 2020, newly discovered Comet C/2020 S3 Erasmus closed in on planetary nebula Abell 33.

Both objects are of similar colors with a ghostly eerie pale green-blue. Both are of similar sizes projected into the same swath of sky. That's where the similarities end.

Comet Erasmus is moving rapidly in our own solar system with a rondeaux just inside the planet Mercury's orbit on December 13, 2020. Will it get Bright?

Planetary nebula Abell33 is a +12.9 magnitude comet approximately 2500 light years away. It is a remnant of a dying star that has coughed up an envelope of gas into a giant blue bubble. The star is still extremely hot and the star's uv radiation is exciting the oxygen atoms in the cloud turning the bubble an eerie blue.

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.
