Small galaxies in Ursa Major

A few galaxies, some not so far away, others a bit further.

In the "foreground" are six galaxies which are at distances varying from 39 Mly (ngc 3972) to 260 Mly (ngc 3921).

ngc 3972 39 MLy

ngc 3913 42 MLy

ngc 3982 49 MLy

ngc 3916 254 MLy

ngc 3977 254 MLy

ngc 3921 260 MLy

The faint fuzzies in this image are galaxies with a redshift between 0.05 and 0.06, which puts them at distances between 660 and 790 Mly.

LEDA 2490407 660 MLy

2MASX J11542652+5517512 776 MLy

Then there are the really faint fuzzies with redshifts around 0.08 - 0.14 or higher, which means these galaxies are 1000 to 1800 Mly distant.

2MASS J11511344+5506592 1045 MLy

LEDA 2494537 1606 MLy

SDSS J115149.73+550258.6 1800 MLy

And finally, there is galaxy cluster [SPD2011] 45352 with its brightest member SDSS J115352.61+551357.9 at a distance of 3040 MLy

Ngc 3921 (Arp224) is a galaxy with a violent past. During an interaction with another galaxy (probably absorbed by ngc 3921 )a tidal tail was formed. Also interesting is the string of bright spots on the right hand side of this galaxy. According to Simbad, these are possible globular clusters, but in a Hubble image, these look more like distant galaxies.

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.
