M9

This object is a mag 8.4 globular cluster located in the southern constellation of Ophiuchus at a declination of -19 degrees. It lies just over 25,000 light years from earth and contains more than 250,000 stars. It spans 9 arc-minutes and is 70 light years in diameter.

M9 is one of the nearest globular clusters to the center of the Milky Way, at 5,000 light years from the galactic center. As a result, the cluster appears a bit flattened due to the gravitational influence of the Milky Way core pulling it slightly out of shape.

This cluster lies at the edge of Barnard 64, a dark nebula, and the cluster’s light is somewhat obscured by interstellar dust. This is why the sky is noticeable darker towards the bottom right of the image.

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.
