NGC 7638 (Gary Imm)

Celestial hemisphere: Northern · Constellation: Pegasus (Peg) · Contains: IC 1483 · IC 1484 · IC 1485 · NGC 7638 · NGC 7639

NGC 7638

This Astrobin Debut Object is located 370 million light years away in the constellation of Pegasus at a declination of +11 degrees. It spans 45 arc-seconds in our apparent view, which corresponds to a width of 80,000 light years.

This object looks like a pair of galaxies, one white and one blue, with a star stream bridge connecting them. The pair could be at the start of the merger process.

At least 5 other galaxies are seen in the background. The orange galaxy at top left (IC 1485) is the same distance away as NGC 7638, but the other orange galaxy just to its right (IC 1484) is twice as far away.

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.
