NGC 4490 is a late-type SB(s)d in Canes Venatici. It has an apparent magnitude of 9.8 and an apparent diameter of 5.9 arc minutes. Along with NGC 4485, it makes a pair of galaxies often known by the nickname of the "Cocoon Galaxies".Each "cocoon" is actually a spiral galaxy that has been distorted by the other. Hints of spiral structure are still evident in the smaller galaxy. These galaxies have already passed their closest approach (perigalacticon) and are now speeding away from each other. A tail of stars stretches between the galaxies, which are separated by at least 24,000 light years. An incredible number of star-forming regions have developed along the facing sides of each galaxy.Both galaxies are 40 to 50 million light years away. Supernova 2008ax took place in NGC 4490 in 2008. *SkySafari Pro

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.
