Hickson 61 - The Box

Hickson 61, also known as HCG 61 or "The Box" due to the unique rectangular shape. Number 61 of a list of 100 compact galaxy groups, compiled by Paul Hickson in 1982.

HCG 61 consists of four galaxies, only three of which are at a similar distance. The odd looking bluish galaxy at the top is NGC 4173, which has a low surface brightness and is much closer to us than the other three. It just happens to be in the same line of sight. The blue stars in this galaxy indicate new star formation. The scattering of small faint galaxies to the left of the image are part of large galaxy cluster Abell 1495.

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.
