NGC 5430

This Astrobin Debut Object is a barred distorted grand spiral galaxy located 140 million light years away in the constellation of Ursa Major at a declination of +59 degrees. It spans 2.3 arc-minutes in our apparent view, which corresponds to a diameter of 100,000 light years.

Despite its great distance away, the galaxy disk presents interesting detail. Particularly interesting is the blue star-like object which appears to be embedded in the bar. Several studies have confirmed that this is a small dwarf companion galaxy and not just a nearby superimposed Milky Way star.

A third arm appears to be extending upwards from the disk, likely caused by the disturbance of the companion.

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.
