Arp87 (Rodd Dryfoos)

Arp87

My first Hubble image. Thanks to Ruben Barbosa for providing the link. I am at my wits end--the clouds are unrelenting. This image is unusual it seems for Hubble--many Hubble images have deep backgrounds loaded with faint and not so faint galaxies. Not this image, however. I don't know if that is because this represents a particularity distant group pf galaxies, or if it is due to only one sub per channel. I tried adding Ha--but the Ha sub was quite weak and noisy. I am fascinated by the clarity of the interaction between these galaxies. I am also intrigued by the two reddish galaxies in the image--one fairly large, elongated spindle at right, and one, small spiral upper left. Both of these are quite red, either from a large red shift, or poor processing! I do wish there was more data as parts of the image are noisy and rough-not like many polished Hubble images.

I am not sure it is real, or just a processing artifact, but the tidal connection between the two galaxies is red on the left half (closer to the galaxy on left) and blue on the right side (closer to the galaxy on the right). If this is a true depiction, it is pretty interesting.

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.
