I was waiting for the comet Garradd C/2009 P1 to rise behind my house, and the night hadn’t cast its darkness on my site yet. Well, by darkness I mean light pollution, but make what you want of it. Anyway, with the sky still blue I shot twenty images, three minutes each, to the most prominent globular cluster visible at my latitude.

The blob you see in the top left is nothing but three hundred thousands stars condensed in a mere 145 light years diameter.

Noticeably, the Arceibo message was directed to this cluster in 1974. I guess we won’t hear back for a while, given the estimated distance of twenty-five thousands light-years!

On the bottom-right of the image you can see the faint spiral galaxy NGC6207, in which a supernova was discovered in 2004. It’s forty-five million light-years away.

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.
