M109 Barred Spiral Galaxy, Friends and Deep Galaxy Field

Acquisition type: Lucky imaging

M109 is a LINER (low-ionization nuclear emission-line region) galaxy, with a strong spectral line emission from neutral or weakly ionized atoms, and relatively weak emission from strongly ionized atoms. In short, it has an active nucleus, though less active than Seyfert galaxies--both powered by a central black hole. These galaxies can turn on though, generating a bright quasar. That would be cool to see!

M109 is about 50 million light years away and over 100,000 light years across. M109 is part of the Ursa Major Group of Galaxies, and is one of the brightest and largest galaxies in this group. It is really wonderful to see all the galaxies in this field, though many of them are much, much farther away than this local group of galaxies.

The three largest galaxies in this field are satellites of M109, like our own Magellanic Clouds: top left of center, PGC37553; top just right of center, PGC37621; right, just below center, PGC37700. Also, right and slightly above center. PGC 2832098 is likely a satellite galaxy based on a similar red shift. Finally, just to the right, and slightly below PGC 24236214, the red galaxy is SDSS J115722.65+531644.3, which is 3.5 billion light years away, based on its red shift!

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.
