NGC 4656

The galaxy NGC 4656, also known as the "Hockey Stick Galaxy," is an impressive stellar formation located approximately 30 million light-years from Earth, in the constellation Canes Venatici. Its name comes from its characteristic shape, which resembles a hockey stick, a result of gravitational interaction with the neighboring galaxy NGC 4631.

This galaxy has undergone significant distortions and features an extensive star-forming region, giving it an impressive and complex structure. Studying NGC 4656 provides valuable insights into galaxy interactions and their effects on astronomical evolution.

The photograph we present here captures the beauty and complexity of NGC 4656, revealing its unique characteristics and inviting us to further explore the mysteries of the universe.

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.
