NGC 1516

This pair of interacting galaxies is located 0.5 billion light years away in the constellation of Eridanus at a declination of -9 degrees. Each galaxy spans 30 arc-seconds in our apparent view. This corresponds to a diameter of 80,000 light years.

It is unusual for 2 galaxies to have a single NGC designation as this one has.

The 2 galaxies appear to be connected by a bridge of faint star streams. The cores appear yellow while the disks contain both blue and purple star-forming regions. It looks like significant star formation is occurring in the disks, which are spotted with blue star clouds.

The bottom galaxy looks unusual to me for 2 reasons. First, the blue oval inner ring, with the bright galaxy core off-center towards the top. Second, the small bright yellow star-like region seen towards the bottom of the disk, looking a bit like a foreground star.

This is the second image of this object on Astrobin.

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.
