NGC 2340 Galaxy Cluster

This galaxy cluster is located 260 million light years away in the constellation of Lynx at a declination of +50 degrees.

This small FOV (23 arc-minutes wide) contains 10 NGC and IC objects. NGC 2340, on the left side of the image, is the largest and brightest of these galaxies. This magnitude 13 elliptical spans 2 arc-minutes in our apparent view. This corresponds to a large diameter of 150,000 light years.

Notice the absence of blue throughout all of these galaxies. Apparently, there is little new star formation occurring in this cluster.

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.
