NGC 7789

This object is an open cluster of 600 stars located 6000 light years away in the constellation of Cassiopeia at a declination of +57 degrees.

Caroline Herschel discovered this object in 1783, which led to its nickname, Caroline’s Rose. It does look a bit like a rose if you look at the image with the left side up. The bright colorful curving line of stars forms a stem, the star groupings and void areas form the swirling petals, and the disproportionately high number of orange giants provide the color. The cluster doesn't stand out as well as many others. It is over 50 light-years across, spanning an apparent width the size of the moon.

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.
