Whale and Hockey Stick from SRO

NGC 4631, the Whale Galaxy, is the edge-on barred spiral galaxy at bottom left. It is approximately 30 million light-years from Earth in the constellation Canes Venatici. Beneath NGC 4631 is its close companion the dwarf elliptical galaxy NGC 4627, also known as the Pup. NGC 4631 has a core of older, yellow stars surrounded by young blue stars. It has a dark equatorial dust lane and many emission nebulae glowing with the magenta of ionished Hydrogen. The central region of the galaxy is a starburst region where new stars are rapidly forming.

At top right is the highly distorted pair of interacting galaxies NGC 4656 and NGC 4657, also known as the Hockey Stick Galaxies.

These galaxies are all members of the NGC 4631 group.

Captured at SRO.

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.
