The Perseus Cluster of Galaxies

We had a very heavy rain on November 8th with 60 mph winds. This finally cleared into an unusually transparent and steady sky. FWHM on the 15-minute Luminance subs was between 1.4" and 2.1". Perfect conditions for shooting tiny distant galaxies. (-:

"The Perseus cluster (Abell 426) is a cluster of galaxies in the constellation Perseus. It is one of the most massive objects in the known universe, containing thousands of galaxies immersed in a vast cloud of multimillion-degree gas.

In 2003 a team of astronomers led by Dr. Andrew Fabian at Cambridge University discovered one of the deepest notes ever detected. No human will actually hear the note, because its time period between oscillations is 9.6 million years, which is 57 octaves below the keys in the middle of a piano. The sound waves appear to be generated by the inflation of bubbles of relativistic plasma by the central active galactic nucleus in NGC 1275.

NGC 1275 has also been forming thousands of new globular clusters over the last billion years out of a cool gas.

This network of cool gas precipitates from the hot gas that infuses the entire Perseus galaxy cluster. In fact, the gas concentrates in the center allowing it to cool faster and that leads to the creation of globular clusters.

Once formed, these infant globular clusters do not remain in the network of cool gas but rain inwards onto the giant galaxy like raindrops falling from the clouds."

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.
