NGC 7490

This Astrobin Debut Object is a face-on grand design spiral galaxy located 280 million light years away in the constellation of Pegasus at a declination of +32 degrees. It 2.3 arc-minutes in our apparent view, which corresponds to a large diameter of 180,000 light years.

I love grand design spiral galaxies. I think they are majestic with their well-defined, outwardly spiraling arms. This one has some interesting straight segments scattered about, especially in the top half, perhaps indicating VV row formation. The arms do not appear to spiral in to the core, instead stopping at the bright yellow circular inner region.

A small blue galaxy is visible in the bottom right of the outer disk. There is a bit of disturbance nearby, although not much, so it is unclear whether this object is a small close companion or a distant larger galaxy. I think it might be a companion based on its odd diffuse shape.

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.
