M105, NGC 3384 and NGC 3389

This image shows a trio of galaxies located in the constellation of Leo at a declination of +13 degrees. This trio is at different distances and the galaxies do not appear to be interacting with each other.

The brightest galaxy is M105, a magnitude 9.8 elliptical (E1) galaxy that is 37 million light years away . The central bright portion of this galaxy is only 30,000 light years in diameter, although its faint outer sections extend out for about twice that distance.

The top galaxy is NGC 3384, a lenticular galaxy located 31 million light years away. This galaxy is 40,000 light years in diameter.

The most interesting galaxy of the trio is the spiral galaxy NGC 3389. This galaxy is the furthest away at 70 million years, and also the largest galaxy in actual size at 50,000 light years diameter. Dust lanes and blue star clouds are seen in the outer disk region. It looks to me like the galaxy is barred but it is not classified that way.

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.
