M77, NGC 1055

A nice pairing of geometries is shown here with Messier 77 (left) and NGC 1055 (right). M77 is 47 million light-years distant, while NGC 1055 is ~52 million light-years distant. Both galaxies are well over 100K light years in diameter; M77 is estimated at ~170K light years in diameter. It's somewhat hard to imagine that NGC 1055 wasn't discovered at the same time as M77, but the edge on geometry must have played a role.

M77 contains an Active Galactic Nucleus (AGN), and hosts a (non-visual) barred structure in the core. NGC 1077 exhibits a huge amount of dust/gas around the disk, with lots of distributed stars in its halo. This suggests a past collision or near miss with another galaxy.

There are quite a few small galaxies in or near the field, and a few colored stars help add a bit of spice to the image.

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.
