PGC 90367

This Astrobin Debut Object, also known as IRAS 20351+2521, is a tiny disturbed spiral galaxy located 0.5 billion light years away in the constellation of Vulpecula at a declination of +26 degrees. The galaxy disk spans 30 arc-seconds in our apparent view. This corresponds to a diameter of 80,000 light years. This length does not include the star stream which extends upward. From our view perspective, the disk is inclined about 35 degrees from face-on.

The Hubble image of the comparative mouseover clearly shows the fragmented arms and numerous blue star formation regions. The Hubble documentation describes this object as a pair of merging galaxies, which could be right. But to me, it looks more like a spiral galaxy disturbed by a smaller companion passing close by. Time will tell if their gravitational forces and relative velocities result in a complete merger or just a significant amount of disturbance.

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.
