The Wale Galaxy - C13 - NGC 4631

The Whale Galaxy is a barred spiral galaxy located at an approximate distance of 30 million light years in the constellation Canes Venatici. It has an apparent magnitude of 9.8 and appears almost edge-on. It has been nicknamed the Whale because of its elongated, slightly triangular shape that resembles the profile of the whale. The galaxy has the designation NGC 4631 in the New General Catalogue.

The optical disk of NGC 4631 occupies an area of 15’.5 by 2’.7 of the apparent sky. The galaxy is interacting with a smaller companion, the dwarf elliptical galaxy NGC 4627, which lies just to the north. NGC 4627 has an apparent magnitude of 13.1 and occupies an area of 2′.6 × 1′.8. The two galaxies were catalogued as Arp 281 in the Atlas of Peculiar Galaxies. The American astronomer Halton Arp, who produced the Atlas in 1966, listed the pair as an example of a galaxy pair or a “double galaxy.” The smaller galaxy is often referred to as the Pup.

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.
