NGC 1618, NGC 1622, and NGC 1625

This trio of 3 spiral galaxies is located in the constellation of Eridanus at a declination of -3 degrees. Although they look like they are close together, all 3 are separated by great distances and are not interacting with each other.

The brightest object in the image is also the closest – the magnitude 3.9 mag blue star Nu Eri, which is 700 light years away.

The image with the largest apparent size in the image is also the furthest away – the middle galaxy NGC 1622. This galaxy is 240 million light years away and is a monster at 240,000 light years in diameter. It is a beautiful galaxy, with a nice yellow central bulge, an inner ring, and 2 graceful grand spiral arms sweeping outward and wrapping 360 degrees around the circumference.

The closest galaxy is at top right, NGC 1618 which is 120 million light years away. This galaxy has an odd, disturbed disk structure, although no obvious companions.

NGC 1625, at lower left, is 185 million light years away. Its disk structure also looks a bit disturbed. Another galaxy is seen at the left edge of the disk. It is not clear whether this tiny galaxy is a companion to NGC 1625, or just another large distant galaxy.

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.
