Lynx galaxy group

This is one of the lesser known galaxy groups. Even Simbad has very limited data on the fainter objects that are visible in the image.

The brightest galaxy, and the only one with notable detail, is ngc 2469, a mere 150 Mly distant. Most other galaxies are at a distance of between 370 and 390 Mly from our own Milky Way, a few as far as 600 Mly.

Ngc 2469, right off center, is a Sbc type galaxy with a clear spiral structure, a core that consists of older stars and arms with younger stars. The galaxy has a diameter of about 31 000 ly, much smaller than the Milky Way. Ngc 2488, left off center, is an E-S0 type galaxy, which means that it falls between an elliptic and simple spiral type. This galaxy is about 370 Mly distant and about twice as large as ngc 2469 (although my data indicates that it has a halo which makes it much larger than Simbad's numbers suggest).

On the other hand, the needle galaxy at the bottom of the image, ugc 4133 is 390 Mly distant and has a size of 150 000 light years, about 50% larger than our own. This galaxy forms a pair with ugc 4134, 392 Mly distant and 102 000 light years across.

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.
